when all the coins go down, I lose a lot because I bought a lot of coins, what should I do so that I don't lose a lot, please give your input, friend?
Only the price dropped but your coin holding is the same. The quantity of your holding do not change along with the price. Meaning, you can still regain what you think you lost, or even gain much more if you will hold. Usually price and value tend to increase over time. At times it would take a while, but it will happen. Though, it wouldn't hurt to keep your fingers crossed...
