And so when you start loving crypto, it is by all means create a continuous learning from crypto, even if it means losses which can also give you lessons too. So i think everyone can really trade, but not everyone can bear losses and that is the reason why some traders chose to leave than to continue trading and keep on making losses.
However, since trading is very speculative, once you trade, you should also anticipate not just only gains but losses too because even skilled traders still lose in trading. Its more on building your attitude too towards your losses. But if you think, you're no longer good for trading because you even maximize committing losses than gains, then better leave or maybe take a break while still learning to make a good trade.
Obviously liking crypto makes us feel like we don't feel pressured for profit adapting to volatile trading. That's what I always teach when someone comes along wanting to start crypto trading and complains to me. So the first question I ask is: get to know crypto until you like all the characteristics that crypto has. The basis for my liking for crypto in the beginning was the freedom of transactions that were in my hands without having to deal with government institutions.
