When i lose my money on trading especially i review my mistake and i will not do it. Losing of money in crypto will give you a chances to be careful again.
Losing money in crypto is very usual. as because Crypto is so volatile and you cannot know when the price increase and when it drops... I am not much involved in crypto trading. but I think traders should only use that much money which they can afford to lose and will not face any problem.
using all of the money in trading is simply not smart.
