Here is my suggestion to become profesional trader
1.Research; before investment you should check the market cap, daily volume, differences between sell and buy order, graphics, roadmap and especially news.
2.Patience; when you invest coin price can decrease, if you believe in coin that you invest, will not sell without gain profit, patience is the key of the wealth
3.Sell in the right time; if you want to make daily trade, this can be app understand from graphics, but one of eyes should be on top of the news, otherwise you can miss great profit, because some news affect to nice pump
Finally i want to say; you didnt gain money easily so dont forget it during the make trading
