If you afford to take the risk (and afford to lose the money if the things go wrong), go for it. Get 1BTC and hold until it goes beyond moon. On crypto scene, Bitcoin has the best potential gain vs risk ratio.

If you have the appetite for even higher risk (and afford to lose too) then you can think on altcoins too. But there, since the risk is even higher, you should really think on diversifying. Of course, with higher risk there's the higher potential gain too (in case it doesn't crumble to dust).
