I think this is a very complicated issue. Maybe my answer is not of high quality. I think the cryptocurrency fell. The best way to make money is to wait for it to rebound. Then you can make money. This is similar to the stocks. Buy low and sell high are the rules of the game.
Buying right now is a good option so it is not a bad advice since the price is not going to get that much cheaper, so we must take advantage of the low prices and get more coins than what we could get if we bought at the all time high, the only problem is that we come from a very intense bull market so most people have spent all their money already and they do not have any more money left to invest in this market which is another reason of why we see stagnant prices.
