Of course, if you think it will increase, why not buy? Of course, it's not like buying at around the $5K level, but if it increases then you are still making money. I don't see any reason not to buy.
Yes ofcourse there's no reason for not buying bitcoin because there can be a huge return and can become profit because of the increase in value day by day so why would you not buy bitcoin if there something profitable in return that can truly help you in your financial needs.
