you need to set the your targets. dont go with the flow, dont follow the crowd. just make ur profit target and right after the exist dont even bother to look at that coin again
this is it , to sell on the news you need to be on top of the news. which requires a lot of time. for most people it is the easiest way to set a target and sell on that target , don't think you can go higher and gamble it all away.
