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.
Winning and loosing alternatively and frequently is the nature of gambling but trading has different methodology here : winning big amounts and loosing small amounts like professional traders do say
"let your profits grow and cut your losses early".
When you are not trading as per the above methodology, it is better to quit trading before losing all your wealth. Quitting trading need not to be permanent. They can learn trading skills and come back again always.
Giving up is always better than struggling. Because there are a lot of other opportunities to make a living and trading is not the only one way for that. But usually people do get struck with gambling or trading and they are not thinking about quitiing even after many losses. One big reason must be addiction, but to save life quitting must be the best option.
