For me i don't really welcome much losses, I try to make sure my trades are good enough and onset and if a trade gives me a loss I will check if I got enough equity I will do hold on the trades and be rest assured it will end up in profit. Well I think the amount of loss I can handle depends on the account size, if I got a bigger account then I can handle up to 3 or 4 loosing trades and if the market doesn't moves in my favor I will know such strategy isn't working for me any longer so I did change pattern of trading
Having that kind of system gives you good opportunities in adjusting your strategy.
Working system is very important as it will give you an edge over those other traders who don't have any. Traders that have capabilities to assess and understand the potential of those assets that they are using for their trading have a better chance to earn decently. It's a good practice to give some time with your strategy as crypto trading is too volatile. Rushing each decision can cause you to lose more.
