A friend of mine has a good mentality. After buying the tokens, he didn't look at the market often. He told me that after buying it, he would treat it as if he had no tokens. This mentality is worth learning.
However, five years is too long. If you want to hold for a long time, you must first understand the future of currency. If you are confident in this coin, please stick to it. After all, five years is not too short. It is safest to choose mainstream currencies. If you find a good time, you can try to stick to it.
