I buy bitcoin as my investment in future, using my extra cash to buy bitcoin with hope they will get me good return in near future 
I also hope that the price in the future will be high because I am also saving and holding on to my bitcoins for the future. I hope I can make a big profit over a coupe of years. I think a lot of people have been recently saving and holding their coins for the up coming halving events and they are really expecting a lot of profit that they will be getting in this event.
Buying would still seems to be much ok for now because the price is still low.
