If you buy shitcoin, the chance the coin will back when the price was high is really hard. So if you want to trade shitcoin, price does matter and make sure you're not buy during bullish season.

If you buy Bitcoin, you don't need to worry about the price because you only need to hold it for next few years, there's a high chance Bitcoin will create new ATH and you will make profit even though you buy Bitcoin at the previous ATH.
