I can't oppose your post because you're saying the same as me but I'm worried for ppl buying bitcoin because of FOMO. They'll make some mistakes they don't know exist until it's to the point they can't avoid losing their investments. It's usually happening when ppl buy at high price but if they're buying to hodl it's a better investment to short sales.
Suppose they will wait for the price to decrease to buy, but what if the price does not decrease but continues to increase? So let's buy whenever we can, and don't think the price will drop after buying because our vision is long term.
