I don't know what your purpose, but it is like you order people to do something you feel doubtful on it. It is not the right way to suggest people, dude. Make sure you feel optimistic on it, then you can suggest other to do the same thing because it is safe to do.
By the way, I think we must feel optimistic about Bitcoin halving. You must already learn the previous Bitcoin halving, right? You must realize that there is significant increase of crypto coin prices after the Bitcoin halving, specifically for Bitcoin. No doubt, now is a good time to collect some good crypto coins before they reach the new ATH. However, the priority should be Bitcoin, it is the most secure coin for investment.
No, we mustn't buy shit coins, it is too risky to have them. Just buy reputable or trusted coins!!
