or may be buy low sell high ?
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
Well, the best thing to do is not to even open the exchange platform. It is enough that you monitor your coins' prices and your portfolio's overall value in your blockfolio account and then leave the rest. Opening up or logging in to your trading platform account will only cause you to sell or buy your coins. That is very hard to control especially if you have the attitude to always compare your coins' growth to that of another.
