If you find yourself in this situation, why don't you ask yourself; what method am I using that is not making things to work out?
It will surprise you that the method might be archaic or that it might not work for this period.
Why don't you change it.
What you have said is right, is good to change strategy when youre losing, but you might change strategy and still be losing. I think if someone is losing what they have to do is find out where the mistake is coming from, if they are able to know where the mistake is coming from they will be able to correct the problem. So it doesnt have to do with just changing your strategy, you have to dictate the problem.
I am sure that there is a very big problem in the fact that today you have for a correct understanding of the situation. Today you need not just to change the old strategy. Today you need to be able to correctly select this very strategy and correctly analyze information.
Thats it, not just looking for another strategy. Another thing that can cause this is when one is trading the wrong coins, I mean buying the cheap coins. Especially newbies are fond of this, they buy cheap coins that promises to get better within a short while, lol. Im not trying to say that buying ICOs is bad, but if you dont know what youre are doing you better stay clear from it than do what you dont know.
