Today,we could see lot of newbies daily entering the crypto currency market and struggling to gain profits.To become a professional trader,what are the characteristics to be developed?
I think the professional traders personal characteristics was self discipline, self-control/know how to control emotion. Those virtues I think is a sign of professional traders which traders supposed to be have it

I guess self control and self discipline are the things which are useful for preventing losses but has no importance for generating profits in trading. But professional traders are being identified only through their performance levels especially by profit levels. Skill on profit generation is more important for becoming professional trader.
Becoming professional trader nothing but becoming experienced trader. People who are just forgetting their trading experience will never could become professional trader imho.
By putting up certain thresholds and stop-losses, you are actually preventing your profit to be burned and has a lot of importance in generating future profits because you know when to stop and call it a day. Reaping up profits alone wouldn't help you becoming a great trader but also knowing when to stop because not everyday is a green day. Also, in establishing such thresholds, you will maximize your profit since you wouldn't be greedy to take them all.
