In my opinion, it depends which coin or token you hold, you should do some research before holding a coin or token for a long time, if you buy a plokadot (DOT) now and hold it for 1 or 2 years, I'm sure you will get a big profit. In my opinion, trading requires a large amount of capital, because large capital will provide large profits, and vice versa. And the main thing in trading and holding is patience.
