Topic: Where can I buy miners? - page 2. (Read 1699 times)

The WeChat/Whatsapp, pay with crypto is a pretty big path to getting scammed (happened to me).

I source mine through Alibaba.  I have found 3 suppliers that have good prices and services.

Ningbo Zanboo International Trading Company - ask for Tracy - Bought many types both new and used from them.

Shenzen Letine Technology Company - ask for Shira - Bought alot of new BTC miners from them.

Shenzen Changcheng Technology Company - ask for Susanna - Bought a used miner from them.

I use Trade Assurance.  Ningbo seems to have the best prices.  Changcheng has the largest selection of used miners and is a decent price. 

Hope this helps folks.

Well since nicehash has always blatantly lied about their returns vs mining elsewhere, I'd suggest to look at a calculator elsewhere.

This link is a good starting point

https://www.nicehash.com/profitability-calculator/

You are asking a personal preference question.  What defines "best"?

There are some basic considerations based on your parameters?

1.  What algorithym do you want to mine?  SHA-256?  Ethash? Scrypt? there are many, and vary based on which coins you want to mine.  If you know you want BTC, you can mine either BTC directly with SHA-256 miners or indirectly by mining other algorithyms and buying BTC.  You have to decide your approach, to each their own.

2.  New or Used?  New miners are scarcer because of demand and production limits, and prices are higher (they dropped recently but still high comparitively).  Lots of 2 - 3 year old used miners coming available as miners switching to more high performance miners or are just shutting off.  Many times, when you buy a used miner, they will actually take it right from the farm and ship it to you.  Beware the dirt and cleaning required but don't take it apart yourself unless you really know what you are doing.  Running a dirty miner isn't optimal but it isn't unheard of.  Also, used miners are a bit more fragile and they may break in transit so you may get a DOA unit.

3.  How eco-friendly do you want to be?  I look at joules to hash ratio and look for the higher efficiency miners.  The S19J 110Th is slightly more efficient than the S19J 100Th from a power consumption, production perspective, but it is more cost up front.  I ended up getting the 100Th but am still debating that decision. 

4.  How much money do you want to spend?  Some small miners (Innosilicon T2T - 26Th) are selling for $1,000 new straight from their website, while used miners are much less (found a T2Tz25Th for like $700).  If you are just playing around and trying to learn, a few small / older miners may be the trick for you.  If you want to start serious mining, that is a different course and cost level.

5.  Environmentals are important to so what is your situation?  Some ASIC's run on 220v so if your location (house/apartment/etc) does have that, you are in for an electrician bill.  Some others run on standard 110v  so figure out your power situation.  But one thing an electrician can't solve for that all ASICs have in common.  They are loud and hot.  So if your spouse likes a sauna and some really nice 70db white noise in the background, you may want to find a hosting location outside of where you live.  They will solve the power, heat and noise issue all at once.  My wife is tolerant enough to let me test the ASIC rigs for a day or two and then off to the hosting location they go!

6.  Are you just in it for the profit or are there other considerations?  Each algorithym produces different coins, which have different values that change every day.  Some miners are at the top of the profit charts one day, the market changes and they become mid-pack.  Asicvalueminer.com or whattomine.com or others can help guide you but set your approach first and then find the miner(s) that fit that strategy.

Any other thoughts on key factors when picking an ASIC miner? 

My choices for ASIC miners are S19J 100T for SHA-256/BTC, HS5 for Sai/Handshake, A6+ or LT5 for Scrypt (still searching for a few but those are tight), just got a Z15 for Equihash and I wish I had a A10 Pro+ 7GB for Ethash, but those are pretty steep.

The used / smaller units are a whole other story so no recommendations there.

Now you are just taking the fun out of it...

But your points are extremely insightful and valid.  Want to buy some ASIC mining rigs (so I can go buy BTC?)   

That $6,500 100TH/s miner costs (current BTC price) 0.2 BTC

PPS per day of 100TH/s is ... 0.00063075
(and it's quite reasonable to say PPS, not higher, since you will have some combination of pool/miner/txn fees)
19.9T diff gives: 0.2 / 0.00063075 = 317 days.
Now that 317 days is FAR from realistic since difficulty usually rises, it's a major under estimate.
To assume that difficulty wont rise over the next 10 months would be foolish.

Difficulty today is 19.9T, difficulty 10 months ago was 17.6T so that's a 13% rise ignoring why it's dropped over the last 2 diff changes.
The 19.9T is due to miners being switched off in the last 6 weeks, that will mostly be on again well before 10 months from now.
The highest recent diff value is 25T only 6 weeks ago, so it would certainly be higher than that in 10 months with miners coming back online and new miners coming online.
But just using 25T, that puts the last 10 months rise at 42% ...

So if instead we used 25T (ignoring any rise) as the PPS value, that gets 0.0005019730957 per day or 0.2 / 0.0005019730957 gives 398 days.

The sites you are using completely (and incorrectly) ignore changes in difficulty for 2 reasons:
1) No one knows what the difficulty will be
2) They don't give you an option to guess or estimate it (like my page does )

That also ignores all the time and cost of running the miner for 10-13 months, so that extends it out longer also.
Then if you have 100 miners, what % of them are actually going to run 24/7 for even 13 months?
Certainly not 100% so another extension to how long it will take.
... to just break even ...

Now if you are gonna make the even worse assumption that you can multiply that 3X for 3 years (as you've stated) ...
What was difficulty 3 years ago (even using the current 19.9T) ... 5.1T or a 290% increase in the last 3 years.
So that completely blows the 3X number out of the water.

So diff increase, power and paying someone for the 1 year+ of time looking after the miner, is expected to be more than 13 months, and ever so likely to be a lot more.
Maybe 2 years is a reasonable guess? But then you have consider how high the difficulty might rise in 2 years and that could extend it out even further.
... again ... to just break even ...

Or simply just buy BTC, as I mentioned in my quote above, and ignore these running costs and difficulty changes.

Edit: and in case you didn't realise, the last 8 diff values have been:
21.4T 21.9T 23.1T 23.6T 20.6T 25.0T 21.0T 19.9T
(the next one could be as low as 14.9T ?)

Kano,

Not to debate too much, but I am finding your point about miners costing more BTC than they will ever mine a bit of a challenge.  I am using a USD based payback calculation, and whether the miner costs $1000 (T2T 26Th) or $6,500 (S19J 100T), the payback is about a year.  Definiately use asicminervalue.com or whattomine.com to help figure out the timeline.  Since miners hosted under adverse conditions last about 2-3 years, that is still 3X over time, even with pool and electricity.  I do very much agree its an over time thing tho.

I am finding there is a big mindset difference between people who like mining verse those who are trading.  Whether its mining to sell or mining to accumulate, its more of a long term, certainty play on gaining BTC (not necessarily the USD or EUR or ? equivalent).

I will add, since this thread is full of it, people reading it should make sure you check other sources for the reliability of web sites posted in this thread.

There are too many posts here by people who created an account to just post here and recommend a site.

Would you send thousands of dollars to someone that some random guy on a street corner, that you've never met before, recommended to you the only time he ever said anything to you?
Of course not.

There are a number of posts here from new accounts that scream 'buyer beware'

It doesn't save you anything to buy from a reseller in the EU, they have to pay the VAT and customs when they bring the goods in, so they are just going to pass the cost on to the you with extra.

Any trusted seller in E.U? To save customs?

I have got all of mine here ,. They are based in Singapore but ship to any address worldwide . I have had shipped to 3 different countries , i would highly recommend  .

Lobo,

I am about 1/2 a step ahead of you and went down the dark path of scammers.  I went to Alibaba and found several vendors who have new and used rigs of various makes and models.  I have established a good relationship with two now who have sold me rigs (and delivered) pretty quickly (thanks to DHL Express).

There are a lot of scams out there for sure, I got bit.  As an FYI, they follow a similar pattern.  Attract you with an unrealistic price via an advertisement on Globalsources or Alibaba, get to you to talk to them via WhatsApp and then ask you for a Crypto payment which will get you a 10% discount.

Some later come back and ask for shipping or insurance, which should be negotiated up front.

Either way, don't do it.  Use Trade Assurance which is essentially an escrow service to protect you against giving money directly to the scammer / vendor. 

There is a lot of used equipment out on the market right now since most new are getting snapped up quickly.  Prices are high, even for pre-orders which if you want new is probably the best way to go right now so you have to be patient.

Let me know if you want contacts and I can pass them along.

David

LOL.

There are a dozen members who sell mining gears here, and another dozen that offer escrow, you need to be insane to think that I have some sort of a secret deal with thousands of people.

I did not claim that you are a scammer despite the fact that I am seriously leaning towards that fact, what I said, is that since you are a newbie here and have no reputation you should accept forum escrow (a service which I don't provide FYI), but you insist on selling your gears without the use of escrow and expecting people to send you money first. if someone is stupid enough to do so, be my guest, I am trying to help YOU sell your gears if you are legit, nobody in their right mind would send money to a random newbie.

If you want to sell your gears, offer the use of escrow, this isn't a command, I don't own the place, I am giving you free advice and you are free to accept/reject it.

We have plenty of stocks available for sales and 100% legit.

Thank you, one webstore you listed above is  hard proof that belong to one of my partner. ( I have maintain that website from very beginning until now, that domain name is also registered by my hand).

I was show some sales record from backend  to one legendary member by personal message 2 days ago.

Found these on asicminervalue
https://shop.bitmain.com/ *Official seller
https://www.innosilicon.com/ *Official seller
https://coinminingcentral.com/
https://akminer.com/
https://www.goldshell.com/

I used https://www.cryptominerbros.com/ before, worked great!

By the way, don't misguiding people here that a seriously online seller accepted escrow deal, that's is joke, at bull market miner are Very tight plus coin value fluctuation is too quickly , not easy way or source to buy it and if you have miner in hand buyer will desperate pay for it.

Why should the seller crazy accepts Escrow? his brain has problem?

Yes, We are scammer, thank you for your compliment.

So like you recommending someone else miner seller are not scammer? who knows the back deal between you and them, As a bystander do you think all folks here is blind?

I like competition fairly, but I don't like someone like you pretending you are fair to judge someone just want keep some shit that seller feeding you. ( can you swear they don't give you some benefit behind?)

Really?
