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.
That is the Basic Knowledge and simple way to engaged in trading but sadly people don't tend to do such because they wanted to seek for the coin that will make them rich instantly that is same reason why many of them lose and fails.
10-20% profit is high enough for a daily profit,at least a 1000$ may give you a hundred to two a day,typical income of regular worker.
