There's nothing to worry if bitcoin's price may drop now coz it will just recover after a week/s and it's a right decision to invest your money in bitcoin. But of course, you don't have to put all your money in one investment only. Maybe you should try to invest in blockchain or in alts also, but do some research before investing into something to avoid losing your money. Anyway, it's really up to you where do you want to invest your money.
