In order to trading, we must look at how much a coin decreases and increases and within what range this coin is moving in the market. We have to buy that coin after coming within a minimum range. And when everyone starts buying this coin, the coin will suddenly go up and you have to sell it at that time. This way you can easily get 10 to 20 percent profit.
Actually you are mentioning now about training but advises in which appropriate for the small time traders and the basic way to save their funds.
This has been forgotten but very functional in daily trading.
Seeking for 10-20% is more than enough to look for too much and in the end will make you lose.
Try to be patience and not greed, this is the problem in many newbie trader as they wanted to be a instant millionaire and what they get?
Loser and bitter.
Never look for too much because that will bring you nothing but wrong decisions.
