I'm a noob, but is it possible for everyone to make a profit, or must there always be losers?
Not everyone did best and that is why others will fail. The real thing that may happen in crypto trading is that someone will suffer losses while the others will win. If we feel that we are not happy with the results, think also the reason that causes such negatives and you'll find the solution that could help to fix it otherwise, you'll still be a loser until the end.
The problem with me is that I start feeling guilty thinking that my gain was somebody else's painful loss.
