From face value it looks like the strategy does not work...However, if you were to compare entry points over 2 - 4 years, you will see that in this period of time that you can't lose. Unfortunately, DCA'ing $1-$10 might not help you to achieve astounding wealth like 2020 and beforehand. There is still opportunity though. DCA $50-$500 a week diversified into the top 10-20 will still yield fantastic returns over the next 2-3 years.
So, is holding top 10 market cap coins a good tactic? In the long run, definitely. The better tactic is to dollar-cost average weekly in addition to long-term holding.
DCA only works if your coin is not going to die. If it is you are slowly losing just more and more money.
Not only does your coin not die, but also your coin should generally be trending up by the time that you want to cash out.. or at least to potentially also be able to hold its value at a price that would have had been higher than the average price that you ended up buying into it.
I would imagine that there are going to continue to exist an overwhelming majority of zombie coins or quasi-zombie coins that generally are dying or going to die.... and having ongoing downward spiraling of their prices, adoption and use-cases - absent their ability to figure out some kind of a use case or to prevent themselves from going into such status... surely many coins already try to market themselves on the impression that they either have a current or a future use case, and so sometimes they are able to keep up some aspects of their price and/or the appearances that they are not a downwardly spiraling project.
Bitcoin is not exempt from such consideration - and surely part of the reason that bitcoin remains valuable (and perhaps one of the only valuable cryptos) is because it has been envisioned and create in such a way that emphasizes the sound money angle and resilience to attack that continues to build and to be reinforced through ongoing building of its network effects (largely
those seven outlined by Trace Mayer in 2015).. Surely there can be various shitcoins that continue to survive, even with bitcoin as the strongest and soundness of monies - because it could take decades and maybe even into the hundreds of years for value to really gravitate and to be pegged on bitcoin or some kind of a coin/project that would need to take over bitcoin's network effects in such a way that it would need to be something in the neighborhood of 10x better in order to actually take over the king.
So what I am suggesting is that if bitcoin is not able to continue on its current trajectory in terms of being the soundest of monies and ongoingly resilient to attack, then bitcoin could also end up as a downwardly spiraling project in terms of its price, and that would be the argument (and likely minority scenario) against investing into BTC and DCAing into it... which so far does not seem to be the case that bitcoin is anything other than one of the best of bets (if not the best) that is currently available in terms of front-loading and continuing to invest into it (asymmetric bet to the upside).. in these likely early days of its adoption... and the main precautions would be to NOT overdo the aggressiveness of your approach towards investing into bitcoin and to stay focused on where the value is at (instead of getting distracted by crap imitator coins and the bitcoin wannabes that are in the top 10 and throughout the coinmarket cap of top coins - absent some short-term reasons to hold or play with some of those coins for spending, trading and short-term gambling purposes rather than long-term investing purposes that should mostly emphasize accumulating and holding bitcoin and perhaps diversifying into some other assets for the purposes of riding volatility - which also could involve a certain amount of stable coins too.. and likely some assets outside of the bitcoin space such as equities, commodities, property or other ways to hold wealth that might fit with your lifestyle and aspirations) so that any of us is able to stay in the game of building our bitcoin stash and continuing to have bitcoin down the road rather than getting tricked or forced out of the understanding that bitcoin remains the king and there is no other asset or currency that even comes close to it in terms of having a strong, resilient and future-oriented investment thesis.
I think a good strategy is to hold the top 10 rankings, a large market cap and reaching more than $ 5 billion is safer, of course we need other strategies, for example we have to be patient and not panic when there is a decline, as long as we can be patient to hold then we have the opportunity to earn big profits.
Being patient and not panicking is actually not part of the strategy, even though these two things are a must for those who are holding certain cryptocurrency assets for a certain time. Meanwhile, looking at cryptocurrencies that are located at a certain rank by considering the amount of volume that has been generated is clearly included in the strategy because it is sought so that someone is not wrong in buying cryptocurrency assets, especially now that there are so many cryptocurrencies on the market which not all of them have to be considered good.
Trying to look around about on the current number coins in the market which it doesnt really signify that all of them would fly even if we do speak about bull run. Holding top 10 altcoins doesnt assure that you could make profits but its better rather than on buying those coins/tokens which doesnt really have any real use case. The most important thing on here is that you should really set up a selling point whether you are holding top coins or not and then buyback when the bear market comes. You could really be able to utilize on making profits without the need on waiting up for long years before you could see some new all time high.
You could eventually buy more in the bottom if ever the bear market approaches. On this way, you wouldnt really be making yourself getting stressed just because of that long wait.
If you do see that holding top coins is a good tactic then it would really be your entire choice whether you would be sticking into your plan or would really be making out
some alterations if needed or something you do see as a better option to be made.
To me it sounds like a real losing strategy to both dilute your bitcoin investment by getting distracted into various top 10 cryptos, including having ideas to value them as if they were something like bitcoin and to contemplate buying more of them on dips, as if they were like bitcoin.
Sure, if you assess something (like bitcoin) to have fundamental value, then you buy on dips and you engage in various strategies to increase your holdings (of something like bitcoin), but if you categorize all top 10 in the same way as you are categorizing bitcoin, then you are both diluting your bitcoin investment and you may well end up losing a shit ton of money, especially if you were to engage in some kind of an equal distribution.. such as using 1/10th of your periodic investment cashflow to buy each of the shitcoins in the top 10 (not referring to bitcoin as a shitcoin, just the others)...and by the way, I don't have any problem with figuring out ways to go in and out of stable coins, as if they were pegged to the dollar (and hoping that they do not lose their peg), but stable coins are not an asset that you should expect to gain value over time, but instead to be losing value at the same expected rate of the dollar - and hopefully not losing more than that (but having perhaps more liquidity options than the dollar - and thus perhaps some greater utility than the dollar).
