Can you make everybody to win in their crypto trading?
of course not, it is impossible if everyone can win in trading, if everyone wins who loses? Basically, when someone is said to be "profitable" it is when they sell their coins at a higher price than the price they bought them at. and a trader is said to be at a "loss" when he sells his coins at a lower price than the purchase price. So if everyone makes a profit in trading, who buys at a high price and sells at a low price? That's how trading works, am I wrong? 
Trading requires experience, knowledge and perfection. It also requires patience if you really wants to win big, but greed is affecting some patience because some people are too greedy and greed is always leading people to the wrong direction by losing the entire money. Always good to take the little profit you have.
