Topic: Best way to DCA 1.000.000 $ into Bitcoin (Read 401 times)

Thx for all the answers.

Would still love to hear thoughts to this:


Now I am sceptical about the DCA part. Maybe it would be better to win 2.000.000 and buy btc for 1.000.000 and to dca the second million

You want a one time thing and huge transaction? Then find an OTC market in your area or try to contact an exchange if they can do that for sure.

Yeah, sure DCA is the best method on this one but your situation differs from everyone. If I own a huge amount, I'll keep that already in BTC and won't have to wait any longer for further price drops.

Whatever it is that I think is low now, I'll have it and the deal's done and I'll move forward to my next step and plans.

I'm not a fan of DCA, but to avoid "sounding" disrespectful to those who recommend it, I would suggest that your DCA fund(which could be in stablecoin or fiat reserve) be used for supporting Bitcoin, by only selling part of the dollar or fiat reserve for Bitcoin whenever there is a significant dip. As a beginner, only buy when you are certain the next price movement after a dip will be a significant reversal or price increase. The only way to be certain is to follow the posts & predictions of "Bitcoin Master"(He may be the one "talking" to you right now).
You may sell whenever there is price increase or you keep buying every significant dip when you become experienced trader.
Our Prediction for you:  Soon, Bitcoin will slightly cross 32,000 and then there will be a major dip after that. You may trade on this.

It’s better spread it on daily basis instead of purchasing bulk every week so that you can average your buy price as much as possible. There’s a DCA on Binance that gives you an option to purchase Bitcoin based on time intervals or whenever price hit a certain price.

You have a huge capital which means you should enter slowly in the market so that you will not pump the price when you buy since your goal is to buy at lower price as much as possible.

This is no hard and fast rule to DCA and everyone has their own technique for DCA bitcoins.

If I was in his place, I would have the market buy 50K every week into bitcoins. In this way, my average price of bitcoin would have been averaged out at a very decent rate and I think this is the best way to DCA.

However, just keep in mind that you do DCA in the bear market or in times such as now where the bitcoin price is not at all time high and also it is in no way near to its ATH. I prefer DCA in bear season and do not buy Bitcoin at all in the bull market when the prices are very high.

It is not a best strategy for everyone as if you are good with trading or just have good skills to use technical indicators and find a next trend of market, you will be able to do DCA better.

Better because you can find better price and time to buy. It is better than people just buy, DCA at whatever price.

Extra fees on exchange is truly a big problem but like I said, two people DCA differently and they will pay different trading fees as well as withdrawal fees. After withdraw your bitcoin from exchange account to non custodial wallet, you will need plam to consolidate your Bitcoin UTXOs that will cost transaction fees too.

Yeah true, using a place like Binance would be a lot better and I do not do weekly but I do monthly and I am quite happy about it as well. Every single month I keep on getting more and more money in return and that's how I see that working as well. Think about it, if we are talking about bitcoin growing, then getting some of it right now must be something good for us in the end, there is really nothing wrong with that at all.

Some people may be not happy about the result all that much, but we could end up with a better result one way or another. This is why I believe that we should be focusing on how we could make a profit from this, if we could do that then we are going to be quite happy with what we got.

To be exact, it would take 20 weeks. That's not such a long time

If you take the right practices in storing the coins, it won't matter if you are storing $1, $10000, $1000000 or $100000000....it will be safe.

How do you achieve this kind of level of privacy? Cold storage & optimal system cybersecurity practices ..and if you don't want the wealth to be tracked, then sufficient privacy measures.

We are aiming to try and create a discussion board for Cybersecurity & Privacy. I recommend checking out the Cybersecurity & Privacy discussion thread, and after doing so, casting a vote on the unofficial community vote to add the board to the forum.

DCA is not necessarily the best strategy, it can be better to do lump sum in some cases.

The thing is that it depends on the price of Bitcoin in the future, specifically in the short term where the DCA vs lump sum is done, and that is impossible to predict.

So, just by price, there's no single winning strategy.

But it's worth considering that DCA usually comes with extra fees in many exchanges, because you might have to pay to deposit each time, and maybe for the conversion each time, where with lump sum you usually pay less in fees overall, plus you might be able to do an over the counter exchange with more favorable rates.

To put it right, what you seek isn't a DCA method but how to place an order. I have yet to see where an order opens ahead of the price set for it. However, we can't for sure trust these exchanges that they won't manipulate price to get it filled before its level. By the way, why would anyone want to put that much into buying a coin and then set the price above its current rate instead of setting it below to be picked up during correction? If price were at $29k and I'm certain I want to go in, I would rather place my buy order below $29k at an available support level. That's the best way to go about it

I think its perfectly reasonable to put some of your winnings into Bitcoin and to start a legitimate business at the same time. Your familiarity with both the cryptocurrency industry and more conventional business channels bodes well for your plan.

You make some valid points, such as the suggestion to consider buying Bitcoin at the end of each price interval. To make the most efficient use of available funds, one can consider purchasing items in descending price order. My only concern is that the plan seems a little too straightforward. Yet, it seems that sometimes the simplest solutions are the most useful. Its possible that wont be an issue, but Im still curious. Anyway, I appreciate you sharing your opinions with the community because they are certainly thought-provoking.

For the big investors, $1 million is nothing to them, but to us it's a huge amount of money and we can do a lot with it. I will be like you, I will only invest $300k in bitcoin, the rest should open a few businesses and diversify assets to generate daily income would be much better to put all of it into bitcoin. Bitcoin has real potential but that doesn't mean it's risk-free so investing the entire $1 million in it is really not a wise idea. Diversification is something we should never forget.

In reality, if I manage to win something that significant, I wouldn't invest all of it in Bitcoin, I will probably invest about $200k to $300k in Bitcoin and use the rest to set up a real-life business for myself so that I can keep getting money from it because Bitcoin might be profitable but it can't be compared with a profitable real-life business because that will always be earning you revenue regardless of the season or the time in the year, so that would be my first priority.

But, since it is a hypothetical question, I would say that the best way is probably to keep buying after every price interval, like if Bitcoin drops a thousand dollars, you should go ahead and buy some, once it drops a thousand more, buy some more, keep doing that until you exhaust your capital but make sure that you are always buying below your last buying price.

$1 million is a significant amount of money, but what's the point of gradually putting it into Bitcoin? I think people use DCA to invest slowly, at a comfortable pace, and potentially indefinitely. $50k weekly means $200k in a month, and a total of 5 months to put $1 million into it. I guess it does take a while, and it is DCA, but I just don't get the reason for doing it this way if a person is ready to put all of this money into Bitcoin.
As for Binance, at least it's certainly not a good idea to store BTC there. If there is an option to purchase BTC and get the money directly into a non-custodial wallet, that's the desirable solution, but it depends on a jurisdiction, I think.

Converting dollars into stablecoins with the subsequent holding of stablecoins is a rather risky operation. Two months ago USDC experienced a ~10% drop against the dollar. USDT is currently trading at a discount on many exchanges. Why should I get involved in such a shitcoin-casino like Binance? My choice is clear - I will choose an exchange that offers a BTC/USD market, especially if my trading strategy is designed for six months or several years.

Of that one million dollars, I want to use 50% of it to invest in Bitcoin with DCA. That means I'll be using around $500k and $ 10k- $ 25k weekly is best because using $50k immediately might raise suspicions from Binance unless you verify your account into the highest level.

You can also use P2P exchanges where you don't need to verify your account in such a complicated way. Using a P2P exchange, you can find a trusted seller but be careful because we don't know the truth.

Don't attract too much attention from people, including exchanges or P2P exchanges because Bitcoin is now so famous that there will be people who want to harm you. Better to do it slowly and safely. That's all that matters. With that one million dollars, you should be able to save the money properly and not only invest in Bitcoin but you can have many investments. And save money to meet your needs because it is also important.

That's 20 weeks of DCA'ing. (~5 months) I don't think that is a suitable time period for this strategy. DCA'ing takes years. Usually more than 3-5 years. 5000 USD per week is a better way of playing this imo. You can keep you money in short term high yield bonds while you are slowly DCA'ing into bitcoin so your FIAT will get less affected by inflation. Stocks is a good alternative too. There are pretty good high yield dividend stocks, you are park your money there too.

DCA method is the best strategy like you said OP with 50k weekly. But I might prefer to buy a dip 100k worth for a start then I can start the DCA method. Using Binance wouldn't be that safe and it might lead to the raise of eye brown of the exchange. I would prefer using a DEx with a trusted P2P guy with liquidity so that transaction can go smoothly without a problem. $1M is a huge amount of money and you need to make your purchase for at least 15 times,it all depends on the price of bitcoin when you are buying.  The dipper the price the more bitcoin you will get and vice versa this is one thing with DCA method.

Actually a good approach but how do you intend to spend $50k in millions to have finished before the market will changes it directions, while not go by percentage than that with $50k. Is a smart move though but it takes time but if you go by percentage you could get it all at the good spot, judging from the last ATH you can physically see that $29k plus also pretty much better place to start buying by percentage. Or better just follow your instinct if you think that is the best then just follow it because no one would bear the lost with you.

@OP, With the current price of Bitcoin, I consider it to still be so low that if purchased now, one can make a huge profit if the price gets to $50k, $80k, or even $100k and above. Having a million dollars now, you would be able to purchase about 33.333 Bitcoin, which is really a huge sum of Bitcoin, and perhaps if one Bitcoin gets to $80k, you will make about $1,650,000 profit plus your capital, which is $2,650,000. If you can get this profit any time Bitcoin gets to $80k, then why would you just want to waste a lot of time DCAing? Well, it depends on what you want, but if I were you, since it's advice that we should always keep some fiat when Investing in Bitcoin, I would also Suggest that you just buy about 20 pieces of Bitcoin, then reserve the rest of the fund in fiat. Maybe you can keep DCAING with that reserve. just my opinion.

You are right but let's go to the point of OP like what they want is a better way to DCA worth 1,000,000 USD.
Before you can use it to buy in Binance, you really need to convert it to some stablecoins.
I want also to add that there are already a lot of ways to DCA now, especially on Binance, they have this DCA strategy and you can configure it based on what you want .

IF

If price of Bitcoin falls to zero, it means the purchasing power of the USD will increase, and with $920,000, I'll be able to buy much more than with $1 million now. However, statistics show that over the last 100 years, the purchasing power of the USD has only decreased, and in the past century, it has fallen by a factor of 10. Do you have evidence that the USD won't depreciate by another 5 times over the next 50 years?

If you win a million, chances are you won't be getting that in one go, but something like 200k a year in monthly paychecks. In that case DCA isn't a bad idea.

That said, knowing that I have 800k coming in the next few years and having only 200k to invest, I wouldn't DCA. Chances are you will not get another paycheck before the bull market, so in that case the sooner you have some coin the better. If I had what I have now, so a house, a car and no debt, I'd put 150k into bitcoin all at one go, maybe dividing it into 3 50k purchases over the next 6 months, in case there's a small drop and I can get more for less.

Thats a good point.
What asset ist as good as btc?
Housing market? I can tell you houses are a headache + a lot of work and the taxes on profits in my country are a joke. I also think this is the time to sell houses, not to buy - but who knows what the prices will do in the future..
ETF? barely beat inflation.
Stay in cash? haha
Gold? nope

I see no second best after btc

$50K per week is 20 weeks if you do the math, but would you set your DCA at $50K all the way?

I think that's already the smart way so what do you want from the other way?

 You've set every week to $50K, but I'm asking if you win $1M is it all for bitcoin DCA? You are not thinking of other assets to diversify.

The most well-guarded trading secret is that significantly more profit has been generated by purchasing new highs compared to any other strategy, and the difference is substantial.

Dollar cost averaging (DCA), as we are all aware, is an effective tactic for reducing risk in the bitcoin market. Therefore, if it is possible that you will win a million dollars. I will not fully advise you to use the DCA method first, and I will only ask you to think about and choose the amount you want to invest in Bitcoin and do it once. This is because the market is still in a bearish phase right now, and if you are buy during this time, I can confidently say that you will benefit. But is it acceptable if you choose to employ the DCA method? I'll just say that you should deposit some money into your Binance account so that you can pay whenever you like each week to reduce your stress about deposits, but for security reasons, it will be better to be depositing $50k to Binance each week and, once you buy it, move it to your non-custodial wallets because leaving your funds in any exchange fully advisable because you be not the only one having control over you funds.

To begin with is very unrealistic to think that if a person happened to win a million dollars then they will invest everything on bitcoin, at most I think someone could invest half of it and then use the rest to pay whatever debts they have, enjoy some of that money and raise their living standards, also I would not use all of that money to perform a DCA strategy and instead I will keep a portion of it to buy the dip in the case the price of bitcoin went down, a good strategy if you ask me as if you put all your money into a DCA strategy then you will be unable to take advantage of the low price if it gets to appear.

to DCA $1m spread in $50k lumps. is obviously 20 weeks

first step is not to just random buy at deposit no matter the price
firstly know where the market is sat at right now

this halving cycles market window is $15k-$70k
and current price is $29k
0  15  30     70
 ||||||||||||||
        ^

right now we are still in the green. so a good time to be buying

i personally would be thinking to DCA more in the green and less in the orange and none in the red
by this i would try to DCA $50k-$25k in orange
and set it to maybe $75k a week now and $100k if the price went below $25k

then on the day you deposit knowing there is a bit of up and down. if today the market is at a more than 5% up compared to yesterday, just wait a little to see if the daily up comes down a bit and then buy.. in the end if no benefit happens you still just buy in before the end of the week.

alot of people will say the whole point of DCA is to just blindly set up an auto debit on your fiat account to just auto buy crypto without stress or worry
where the aim is that you dont care about the price this year becasue DCA is about hoarding for retirement in 20-40 years so playing the temp prices to maximise yield now is a stress thats not needed.

however some like to try to maximise benefits upfront..
EG imagine a mortgage that every 5 years you negotiate new rates.. its better off while interest rates are <3% to pay down more of your loan and have less debt. instead of just ride the mortgage out autopilot style. there is no point just paying whats presumed each month and then later realise your paying out more but not paying down your debt any quicker when interest rates rise

At $1 you could buy 1 million BTC   At $1,000,000 you could buy 1 BTC 

thanks for all the input.
Interesting that so many replys are like "buy a big chunk now before the price goes up". What if the price goes down?
At the current price I could just buy 33 btc. At 20k I could buy 50btc - that number sounds way better. But on the other hand, what if the btc CEO raises the price to 50k and I miss the "btc under 30k boat"... xD

A hardware wallet etc is self-evident for me.

A million dollar to be put for DCA just like that? I don't think so I will be able to do that if I were you. I would just buy Bitcoin at best possible rate and put them in a cold storage. I am very positive about the DCA methodology and in fact keep it as one of the favorite all the time. However, in this case scenario I am not staking my million dollars just like that because I do not want to lose such big amount in single go. Rather I would just trust the Bitcoin and the periodic hikes that Bitcoin gives us due to its volatility. Over the course of time it will definitely go above 100-200% easily, and I would be more than happy to wait for that to happen as our legends in the past did. If I keep doing DCA then it may happen I start losing in between due to large volume. I just dont want that risk. Either I would secure my million or I would just wait for it to grow in the jar just like that.

Do you know why you're an idiot? Because if I ask you to give me the link to the BTC/USD market on Binance dot com, you won't be able to find it. Also you can't find there support for SWIFT or ACH for transfer USD.

If you lost $80k, what would you do to get it back? What do you base it on or do you have any evidence that bitcoin will rise to infinity? You are so focused on profits that you forget about the risks of bitcoin, don't forget that the higher the return, the higher the risk. Bitcoin can be of great value but also can have no value, the future is unpredictable.

Even the basics like depositing money on exchanges and buying bitcoins, if you still don't know how to do it then you are not ready to invest in bitcoin especially in large quantities like the OP is suggesting. And the main question OP wants to ask is there is a better way to invest and DCA in BTC with $1 million.

Someone with that much money don't need any DCA, if I have such big amount of money and currently Bitcoin is under 30k I will buy some Bitcoin, up to 10 BTC and wait till August maybe there will be a lower value for Bitcoin and buy more, your case is different from many crypto investors, most people are not millionaire, they are only trying to be one.

DCA is very important for people that work for a salary per month or have their businesses, we are still struggling to buy 0.5BTC compared to Micheal Saylor who buys Bitcoin in numbers.

If you have this high amount of money just buy bitcoin and go keep enjoying your life, that's enough to make all your worries go away, you are already made.

If someone wins a millions dollars then he/she will most probably get all those things he/she dreams having since childhood. And, let's suppose that the needs of the person require $500k then he/she will be left with only $500k to invest in Bitcoin. Now you should have a proper plan to DCA the remaining $500k into Bitcoin.

For someone like me the smartest way to DCA the money would be to invest it in Bitcoin when it faces a dip, and I would say that Binance may or may not work for such operations and that's why I think a good investor would often try to find other alternatives as well rather than relying only on Binance.

But, if you still want to go with Binance then you should reduce your sending amount to $10k maximum and each week you should set at least limit orders on different price ranges. Keep in mind that setting way lower price limit would not be a good choice because sometimes those limits are not reached and your order won't get filled.


Who said that the OP needs to deposit USD directly on the exchange? There of course has to be involvement of P2P trading for depositing the USD into Binance. For USD related trade P2P still works like a charm and anyone who knows that will probably go with that route.

Binance dot com has no BTC/USD market. You can't deposit there $1m USD. Lol

Smartest in what?

You buy Bitcoin in Binance, you need to verify your account, and withdraw the coins back to your cold storage, that's already enough.

If you're privacy oriented, you must use decentralized exchange and mixer. It also depends on what you want to achieve, you can evading tax by doing that, it's one of the example.

If cash is on hand ready and I'm about to plan certain amount like putting that million on Bitcoin. Yes, DCA is a good strategy but if I think that the price now is as low as it can be then I'd certainly do everything to buy that.

Whilst it's a good to lumpsum it, the problem mostly with exchange is that when you're a buyer and you get that much transactions. That's where you will trigger them and could ask for more docs compliance.

That's pretty much it. If you think that Binance is the good exchange that buy with that money, one thing that you'll need to accept is the possible more IDs that they'll require you.

DCA as you've mentioned, since now we are still in the bear market season where the bitcoin is dip, you can DCA onna weekly basis and buy to hold gradually, but we cannot predict what may come next anytime for the market to rise or not, you can also make the buy at anytime from now and hold since it's a long time investment, the more we may be buying the higher the market price may be going, so taking advantage of the dip to buy twice may be right since we are likely not going more dip than this.


I will advise you to make use of a decentralized wallet to hold your bitcoin, though you may use an exchange in getting them but once exchanged, then you move your asset to a decentralized cold storage wallet, it's not safe to have your long term investment on centralized exchanges.

Binance dot com has no BTC/USD market bro  

I would never trust centralized crypto exchanges like Binance when it comes to depositing big amounts of money(even though Binance has a p2p market).
The best way would be to find a trusted trader with big liquidity on a decentralized exchange and make deals with him.
You can do whatever you want with your money. I don't have 1 million dollars and I have never dealt with such big amounts of money, so what do I know.


Yes, that's right, but why would anyone buy Bitcoin at 90K USD? I guess that the trader(or a trading bot) made a mistake with this 90K/BTC order. Maybe he had mistaken the buy order with a sell order and wanted to sell BTC at 90K. This sounds stupid, but who knows.

$50000 per week is a non-optimal bet for your relative small $1m capital. What if in 10 weeks Bitcoin price hit $8888?  

Try this:

If your capital is $1 million, then divide it into 1000 equal parts. Place price*amount = $1000 limit orders with ~$100 price step (the price step is not optimal, but simple)

For example Limit buy orders
price     | amount
$29000 | 0.0344 ~ ($1000 / $29000)
$28900 | 0.0346 ~ ($1000 / $28900)
$28800 | 0.0347 ~ ($1000 / $28800)
$28700 | 0.0348 ~ ($1000 / $28700)
... etc.

If the price goes down, your orders will be executed. If the price goes up, continue placing orders higher (place every day or every week) according to the specified strategy.

First, thanks everybody all for the answers. It looks like my question wasnt clear enough.

1. Bitcoin price wise nobody knows shit about fuck. DCA 50k/week are just 20 weeks. The question is not if u think its better to buy all at once or in 2 weeks or on the 11. of december^^

2. Why I asked if a limit order is the way: a month or so ago I saw that someone buyed a bitcoin on binance for 90k/btc or something like that (forgot the correct numbers). He made a market order and it got filled at that funny price.
So, the question is: btc price is for example 29k. I open a limit order to buy for 50.000$ at a limit of 29.1k/btc than there is no way that my order gets filled above 29.1k - Is that right?

฿ == $+∞

How about... $920,000 and 2.625 Bitcoin?

If the price of Bitcoin falls to zero, you will lose $80,000. If the price of Bitcoin rises to +infinity, your $920,000 will become worthless.

With such a financial level and learning about the investment field, I don't think that person needs advice on DCA form, if I own those things I think the financial position is quite good for me. Search for some places that can help and the rest is for other things like entertainment.



But the DCA story doesn't have to be complicated as long as you're ready with the capital, time to implement, monthly, weekly or daily form no matter what. And the investment also needs to be considered from the beginning in terms of the expected return target and the degree of holding the investments. Buying btc today is not difficult, when an ordinary person with just a few training courses can easily buy and manage it, but now to be more realistic, I will continue to think about the problem for $1m.

If your capital is $1 million, then divide it into 1000 equal parts. Place price*amount = $1000 limit orders with ~$100 price step (the price step is not optimal, but simple)

For example Limit buy orders
price     | amount
$29000 | 0.0344 ~ ($1000 / $29000)
$28900 | 0.0346 ~ ($1000 / $28900)
$28800 | 0.0347 ~ ($1000 / $28800)
$28700 | 0.0348 ~ ($1000 / $28700)
... etc.

If the price goes down, your orders will be executed. If the price goes up, continue placing orders higher (place every day or every week) according to the specified strategy.

If you win or 1M$  the dollar would you like to allocate for bitcoin and hold it until the bull run arrives? Because if I ever Igot that amount of million dollars, I would separate 250k$ that I would provide it for bitcoin immediately. And I will use 50k$ in day trading and the profit I will get  it on day trading I will apply DCA for other potential cryptocurrency besides Bitcoin. Then the others are for the personal things I need in life such as house and lot, cars and business and other good investment such as real estate and mutual fund something like that.

For retail investors like us, 1 million USD is quite a large amount and investing in bitcoin requires careful consideration and planning as well as knowledge, otherwise it is very easy to lose money. If it were me, I would DCA weekly like you and I would use binance to do it too. Because with large buy and sell orders, centralized exchanges are still safer because of high liquidity. But you shouldn't leave your bitcoins in binance, always transfer them all to your hardware wallet after completing the buy order.

If you feel the price set today is the best to enter or the market price will increase higher why do you have to do a DCA, you can immediately buy Bitcoin at once or half of the amount of money budgeted to buy Bitcoin. The best way according to each user is always different. If you ask me, I prefer to buy when the price is lower than yesterday, the potential price increase will be bigger based on the movement in the market. You can apply the DCA strategy based on price movements on weekends. You can enter the market every Sunday by setting order limits.

You want to buy a million dollars and you are going to set a limit order? I wouldn't eat my head off with that, better to set the orders at market and that's it. What are you going to do if you set a limit, and the price starts to go up? Not buy that week? After all you are doing DCA, aren't you? Order to market or for the best and go for it.


If the origin of the money is clear, in this case from the lottery collected at your bank, there should be no problem. I had thought that maybe a DEX would be better, but for these amounts the bank and the tax authorities in your country are going to keep an eye on you anyway, so I think that in this case CEX would be better.

It all depends on how well you can justify the source of your 50k per week.
Binance will undoubtedly ask you for EDD / SoW type documents for such amounts.
You also need to take into account your country's tax policy if you plan to resell it one day.

If you really want to go through a CEX for these transactions (indeed volumes are likely to be a problem with most P2P solutions), you should first contact them and negotiate some VIP status, so that you have a little more professional and personal support in case of problems.

DCA is buying at any price at the time, not the best price. Buying at the "limit" price means that it does not guarantee you will be successful buying bitcoins on a regular basis. Better yet, buy at the "market" price every Monday.

Considering it is a large amount of money, make weekly withdrawals and use multiple hardware wallets or secure with multisig.

Note that depending on the price you set the limit order you might not get any bitcoin at all.

You can just buy at market value to make this a set-and-forget thing knowing that you will end up with bitcoin at the end of the day.

Ah, and remember to withdraw it to your own wallet. Some exchanges offer auto-withdrawals after you have more than a specific amount.

Indeed, in your words there is a certain common sense. There were many cases when people who won big sums of money in the lottery spent everything very quickly, lost their previous savings, property, became debtors and simply ended badly. Therefore, if you have a lot of money, there may be temptations for rash spending on unnecessary junk and extra trash. Perhaps the strategy of buying bitcoin immediately with some of that money doesn't sound stupid at all. Of course, if desired, btc can be exchanged back for fiat and spent (of course, with losses during conversion), but spending it will be a little more difficult, because this is already an investment and extra actions during the exchange will slow it down a bit. But you can do it differently (roughly as OP described): draw up an action plan, allocate an amount for investment in btc, buy btc once a week for a certain amount. I don’t think that someone, having become a millionaire, will spend time on daily purchases bitcoin, so 1 time per week or per month is quite acceptable. The amount of 50k also seems quite acceptable to me, although it can be divided by two. Should also take into account the current trend in the cryptomarket: in a bearish market, as it is now, it is better to buy at 50k, because bicoin is cheap, and in a bullish one, it is better to stretch over time and for a smaller amount, like 25k.

Well, if you ask me, I don't think that there is a particular way that is generally accepted as good, or the best way, you just have to do it the way you think fits your style in investing, like myself for example, if I wanted to invest the entire one million dollar in bitcoin, i did first invest like 10 percent of that amount considering the season we are now, that is that we are still in a bear season, so the chances that bitcoin price will still drop is high, so i did invest 10 percent first, and i will use the martingale strategy for the rest of the money.
Like anytime Bitcoin removes like $500 to $1000 from its price, i did invest a little bit more than what i invested in the previous time.

For example, my first investment out of the entire sum of one million dollar was 10 percent, in my next investment when the price of bitcoin drops more than $500 to $1000 below its previous price, i did invest like maybe 10.1 higher , that is 0.1 percent higher than what I previously invested, and in the next round, i did invest like 10.15 percent , just like that until the whole money is exhausted.

Like I said before, there is no generally accepted way that is the best way, you just to find a way that is best for you, or you think will work best for you.

If you win a million dollars and decide to DCA 50k, It will take a lot of weeks before you will be able to DCA enough. And because of how quickly money can go as it comes, it will better for me to just budget what I need money for, then invest what is left in bitcoins and then continue by the DCA strategy to continue to accumulate more.

Keeping that amount of money for weeks is dangerous not just because it can get missing, but due to fact that it can be spent on somethings that suddenly come up when you have some money. You do not always need to buy bitcoins by DCA.

lets say someone wins a million dollar and wants to dca 50k weekly into bitcoin.
What is the smartest way to do so?

I know nothing and would send 50k to binance each week and set a limit order every monday. Is there a better way?

Thx
