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. This is actually crazy in my own opinion because the way Bitcoin is structured, it is more better and more beneficial to hold for a very long time unlike all this alit and shit coin that blossom for a very short while, and crash drastically later, so utilizing the DCA accumulating strategy on alt or shit coin is really a terrible idea too me because for you to use such a accumulation method, it shows that you are going long term, and holding alt or shit coin short term is very dangerous, talkless of holding for long term, it is really a terrible thing to do as an investor.
So it is best you backtrack on such idea of yours if you care for your hard earned money.
