I have not seen anyone try DCA with altcoins, and I do not know whether it was a successful strategy or not.
1000 dollars is a good amount for a beginner. If you could do DCA with Bitcoin, it would be better. Stellar has not reacted well in the past years, so what is the reason for you to invest in it?
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.
