SHOULD I EVEN INVEST IN BITCOIN?

Yes you should invest in bitcoin, it's at a good price right now. I recommend you to invest after fall like 10% in last 24h for short sells, if you're going to keep it for some years, just buy it right now.
Im in bitcoin since end of oct 2016 and i wish i didn't sold my btc in july 2017....i bought after it and i didnt sold when it was 16k....i was dumb, now bitcoin its at 3k again, damn.
Invest with responsibility, never go all in with your money and write a goal to sell !!!
good luck
