Even crypto trading experts cannot make everybody to win or earn big profits from their crypto trading at the same time because, for some traders to wait till the real bull to show up in the market, it will make them to feel they are about to miss the opportunity and it can lead them to loose no matter what you do to help such trader.
This is not realistic to have a world where every crypto trader is going to make a profit. Trading is a zero sum game, our profit is somebody else's loss. The rapid changing prices means that every day people will see their positions making a profit or a loss. This is still unrealized gains or losses and as long as the position is not sold the money is not realized. But still it won't be possible to have a world where everybody is making profits. The money has to come from somewhere. Also the crypto trading expert themselves are not going to be able to make a profit from every trade. There will always be losing periods, that's just part of the game. The important thing is to make sure that our winnings are larger than our losses.
