That a very great idea, I am totally agree with you, I crypto market, Any thing can happen, Not just 1$ it can reach to 10$ in second, just like the previous dump from 0.20$ to 0.03$ in one night. Also With the buying low and selling high, not every time is perfect, I lose much more. Great Idea Keep it Up and you will see the result one day
True, it is very unpredictable, the best is to set some realistic target and then exit on that without much of thought and speculation, else forever we will be in a loop
