As I learn market does not change as we need and our hurry.Main thing is waiting and giving time to do it.So be patient and wait for bitcoin price go up.
This is the main thing that we face in the market is price going down.There is nothing to do.News can change everthing.So as I think first of all we have to learn about market cycle if you can observe it properly you will loss never.Please google and download it and observe it.
And next thing is panic selling.It is the next mistake both you and I do.None can do a 100% prediction.So the best thing is if you get the enough proft you had better sell what you have.
If you have good practice of above two facts you can wait wait for bitcoin price go up.Else you will be loss.
