Many people lose because they let their emotions do the trading instead of having a rational mind when doing it. Starting is the most difficult part for me because you would be excited and then disappointed afterwards because you are greedy so you don't want to sell even if you already have a big profit and then see it slowly go down until such time you are already at a loss and again hope for it to go up only to be disappointed when it continues to go down and being a newbie, you would be thinking if trading is really for you.

Those who learned from their mistakes come back up with a strategy but still a number of people who attempt to be trader just sold their position and then left the crypto world and I would assume that many are doing it now seeing the price continuously go down.
