I want to share my trading strategies with you. If i have 4000$, then i divide this amount into 4 parts. And it means my every worth of 1000$. If my trade is going opposite to me, then i use the second portion for average. And i invest my money in different coins. Because if i struck i one coin then the other coin recover my loss. This is my strategy for day trading.
But what about if you invest on a potential crypto currency? I know that it is really hard to predict the price of crypto currency but crypto like BNB, Doge, ADA are more profitable at this time. I think $4k is enough to invest on these coins.
