Lot of noobs traders , don't control their emotions and make worst mistakes : buy at high price and sell at lowest
how to control this ? = put orders (buy/sell) and close the platform
if you buy high and sell low you loss your btc. buy low sell high it's best topic for trade. but how you can now that coin price increase. if you can guess don't have any mistake. every coin price increase and decrease so if you buy don't worry you need wait.
