Those who are big investors basically invest with more money or formed money, but the person who is a small investor how to invest the accumulated money. That's why DCA method is the best and easiest method for both small and big investors, if you invest small amount regularly then your portfolio will be very heavy.

Something that is there to understand is that,
Most of the big investors out there were already huge in the society before they dived into the cryptocurrency niche for Bitcoin investments. Else, how do you hear about people buying up to a 100BTC if they weren’t already made in the society.
DCA offers this same opportunity but with a less aggressive approach and one that spans through time. You get the chance to consider all options and be comfortable putting in just enough to grow your portfolio and grow through the process of investing with ease.
