I think if a particular strategy is not working again them I believe you should change it, maybe due to current market situation that's why your strategy is no more functional then do more research and try to change your strategy. I cryptocurrency I don't even believe one strategy will work for you foreve since the market changes then you strategy should also change if the formal one is not yielding you more interest again.
It is really involving trial and error and this is a must thing because this is where you do really make yourself improve throughout your trading career.Lossing in consecutive manner is something that everyone do experience but doesnt mean that you would need to quit up.
Just sustain yourself and try to look on what are the things become wrong because this is on where do realize that there's something wrong with your trades or analysis and try to make out
some reverse and you will find out.
Try to sustain yourself with experience that you had gained in the past because quitting isnt a solution to the problem.
