To learn to trade in crypto, there are lots of tutorials that we can find on YouTube, so we can easily learn them. Usually beginners always want to get profits quickly, and easily panic when a dump occurs.
My advice is take profits in the trade, don't be too high, immediately take profit if you are already profitable and don't be in a hurry when you want to buy more coins.
In this crypto, the price has very high fluctuations, so don't panic easily when the price of the coin you hold decreases, let alone selling it at a low price is the wrong decision.
