Funny you should ask. Before I became a successful trader, I have lost... countless of times. However, each loss has helped me in improving my strategy. What I have realized in my 4 years of trading is that you will lose, eventually. However, your next step of action after every loss depends on how much percentage of your account you lost, which in turn depends on how much you risk per trade. a person who loses all of his accounts entirely is most probably over risking/overleveraging. I have heard of traders who risk over 30% of their accounts per leveraged trade on bitfinex. That's hilarious!
So, yes, I have made a lot of losses in the past. However, I have moved past that now. I still make little losses of course. But these losses are very minimal and take a very insignificant part of my account. however, when I do profit, I profit big.
the key is to find a strategy that allows you to win big in case of good trades and lose small in case of bad trades. that's what my strategy is all about. Also, i simply don't leverage anymore. that's because in the real sense, leveraging in crypto can stop you out in a matter of minutes because of the high level of volatility. Hence, with this volatility, you don't really need leverage to make a lot of money.
I hope you get back to crypto-trading soon. however, this time, it may be better for you to use a broader approach and think long-term.
