The disappointment of losing a trade is a lot and it kills an individual if he loses a major chunk of his investment but at the same time we should know that a person only loses when he sells in a loss.
Losing money overnight is something that is possible in crypto but not with the potential currencies. If a person invests in scam coins and hopes to make money then that is his mistake.
Similarly, every time we lose money while trading, we tend to learn something new. The only thing we have to do is not to repeat the same mistake again.
I have also lost good amount of money in trading cryptocurrencies but I am still here and learning and still trying with whatever I have to make money trading crypto.
Running away is only true if you will not hold any crypto for the rest of your life. But for most of us here, we need to face the reality of trading and learn from our mistakes. Mistakes will give us new strategies on how not to repeat them again. I don't think any trader here only has winnings in his trading, at some point we lose and that's part of it. But the difference is the degree of such loss. We can minimize if you have at least plans with your portfolio. Don't let it sit without doing any follow-up with the project.
