in this case I usually use the short term method but not by selling 100%, I usually use 100% of my funds to buy one of the coins and wait for the coin price to grow until it is time to sell, when selling, I will not sell all the funds me, but I only sold 70%, the rest are waiting for the right time to be sold again what if the coin starts to grow, this may be just a basic method that I can convey to you.
This is one of the right strategies to take advantage of. We don't know exactly when prices will fly or fall. The choice is yours, when our coins are profitable to sell, then we make a sale. But leave some, for us to get the next profit if the price rises again. But if, on the other hand, prices go down, we will remain calm because most of our capital is safe. Or even we already benefit from our first sale.
