I just share my experience with how I trade, and I also trade in this cryptocurrency with only a little capital. And maybe the trick is like from the Doge coin trade below:
-Buy Doge coins at a price of 0.31 dollars with a capital of 100 dollars
-Sell Doge coins at a price of 0.32, 0.33, 0.34 dollars and so on
For me personally, selling cryptocurrency coins is the right time when the price of the coin is above the price when we bought it and provides a profit that we think is enough to be withdrawn.
Enough here is very complex, there are those who profit 10 dollars immediately withdrawn and there are those who profit more than 100 dollars have not been withdrawn and maybe they are trading in a long-term style.
