yeah you can buy bitcoin because bitcoin is very profitable nowadays because price will be sooner rise up and recommend that buy bitcoin in huge amount and then hold it for the future and i think you can buy bitcoin from your near friends who use bitcoin through cradet card .
Even if not profitable in short time, bitcoins are profitable in long term plus I think most people buy bitcoins because they want to do bitcoin gambling. Since bitcoins gambling is anonymous yet safe and over all for others it is provably fair. I personally prefer BTC gambling over other forms like bet365 and all.
