I don't think someone can actually leave trading just when there are so much good projects to invest with.
If you got into crypto trading, that means you have been into bitcoin for more than months already. I don't think you would want to back away from bitcoin for good, you will always come around.
That is true. If you can win 55% of the time and lose 45% of the time but lose less, you will win in the end.
That's basically a worthless assumption since there is no way to predict the outcome of your potential profits with gambling.
The only certain thing is that in the long run you have greater chances of losing with gambling. There have been plenty of people trying to find methods to win with playing dice for example.
Their "fantastic" method was working till they lost big time. It just shows that dice is a 100% luck based game. There aren't any methods granting you guaranteed profits.
Of course, whale gamblers with a massive stash can continue martingale for quite a long time, but even they will run out of coins since the amounts only get bigger and bigger. Even that isn't enough to guarantee you any profits.
