Buying as much as Bitcoin at current price  is long term investment. Buy and then just forget you have them. Lol. I mean after buying coins, just hold them until the price is is above 500+, 1000+ is even better.
Does it have risk? Of course! every investment has its risk, it doesn't matter whether you invest your money on Bitcoin or other currencies, there's still risk. It can't be 100% safe.
