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.
yes i think winning and loosing is the part of trading you cannot make money every time you have to compromise some thing and must book some lost,but i does not mean to stop trading, if you are continuously losing money then you should try to change your strategy of trading but leaving trading is not a wise decision.
