I quiet agree with you because the fact is that DCA knows kind of investment plans doesn't work for shitcoins because some of these coins the growth rate over a given period is very low so in terms of bringing back value on investment is not there so applying DCA to such investment will be wast of time
Actually the DCA method is always suitable for buying any asset in terms of investment, but it will be more useful if the method is only used on assets or coins that have been proven to be good like Bitcoin so that the steps we take are really useful in the long run. Because in general the method is to buy with the ability that we have so that it is not at all burdensome for us as buyers, but if we do it on coins that are not good, of course the method is useless because we apply it to the wrong assets. So just use the method in collecting Bitcoin and consider it a smarter investment step than our own life.
It maybe generally used for any suitable asset but it doesn't mean that its also good to apply on some shitcoins out there since they are just wasting their money also effort if they think about paying some attention with those scams.
If they used it for those ideal asset like Bitcoin then provably that they will never be wrong from applying that method in that coin.
This method will really be useless if those scam devs do their rug pull schemes that's why its better avoid doing shit stuff with those thing and just better focus on more realistic investment with Bitcoin.
DCA is a strategy for purchasing investment assets periodically. However, what is certain is that the asset to be invested in must have a promising market cycle or volatility. Because if, for example, we do DCA on altcoins or what are usually called junk coins, it is clear that this will not be effective. Because Trash Coin certainly doesn't have a definite cycle like Bitcoin, so the price of the Trash Coin we buy could be zero. Because the important point we have to remember here is that altcoins are centralized, which means that at some point the coin can have its liquidity taken away by the creator of the coin. So clearly the price can drop to zero. If that's the case, we will definitely experience total loss and won't be able to do anything. That's why I don't think there is an effective purchasing method for investing in junk coins. Because in the end it will definitely remain the same, namely you will experience losses.
In contrast to bitcoin, as we know, bitcoin is decentralized, which means that no party can take liquidity in bitcoin. Therefore, the potential for Bitcoin to experience a price decline to zero is certainly quite impossible. Moreover, currently Bitcoin has gained the trust of many people and even countries. Therefore, this will certainly strengthen Bitcoin so that it can continue to experience price increases. Therefore, Bitcoin investment is suitable for purchasing with all kinds of strategies.
