For me is Bitcoin the best investment I ever made. I bought some years ago and still holding them.
Best investment to me either so far although I bought some of it when the price is quite high but I don't regret on buying it. Because I was able to some decent profit already and I've got the ROI already for a very short amount of time. This is also a very good way to buy things online that you need as long as the seller is accepting btc for payment.
