Passion is what makes a trader to be depositing into crypto account to place a trade even when she's still loosing, passion makes it easier for trader to look at charts, place order even when his eyes are closed. When a passionate trader loses, he's happier, when he wins, he's more happier. He sees nothing wrong in crypto ecosystem at all and loves every little dip and cherish every little rise in price.
Such passionate trader is the only user that could be successful in the game because he's going to pay every price needed to be profitable in the crypto industry.
I'd say interest more than passion. Passion is when you put enough effort, so the outcome of what you do is mostly good. But apart from interest that I said earlier, I think the word desperate or addiction is also valid. Placing an order even on close eyes is crazy. I think that is too much even a trader has a passion. There are automated bots for trading but I'd say they are another story anymore. We are only talking about manual here.
No one will be happy losing money. I think being passionate has nothing to do with this. Maybe we can only say that they will be sport enough to accept it easily. Besides, they can also learn from it.
