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.
thats a good way to trade but you also have to consider btc price when trading altcoin. This way of trading can be easy when the market is flatlined but whenever there is big movement in btc, this can also be counter productive. Going with the market is probably the best way to trade and predict the movement as long as you consider the losses that can also occur if prediction is wrong.
