That's a bit strange, and I just saw that there is such an allocation of DCA every month that ranges from 1000$ for the three cryptos it does. It is not surprising that when the bull itself comes or bitcoin rallies together with altcoins, Op will make a lot of money.
I hope I also have that kind of allocation every month, unless he is a rich person, his salary is high, he is an employee, or he has a source of income. Good luck with what OP is doing.
DCA is an investment strategy and can be used by everyone, with any asset but an investor must identifies that asset is risky or safe to invest money in. By considering it as an investment asset, it requires a little bit long time of holding, so risk must be low enough to accept. Because if risk is high such as the altcoin can have rug pull or high inflation in tokenomics design, it is terrible to invest money in it, hold it for a long time.
DCA with altcoins is more considerable risky than DCA with Bitcoin, because they have more risk to lose value or even die, compares to Bitcoin.
If you DCA in bad
top altcoins like Terra, and it has a death spiral event, DCA with it will only bring you from a small loss to bigger loss and nightmare at the end.
