I doubt there's a trader out there that haven't both lost and gained from trading, for you to call yourself a trader you must have experienced both as they help in building you in your trading profession. The reason the numbers are high is because we have noobs coming into the industry daily and jumps right into trading without having any prior knowledge and for those with the knowledge, they lack the experience of trading the crypto market.
The cryptocurency market is different, her volatility isn't like any other which is why many experience traders in other market still find it hard to cope here. Personally I have lost quite a huge amount of money from trading as well have many same too. You can be on one side although you should always make us your profits are higher than your losses, that's what makes you a successful trader.
