my buddy invested 150k on bitcoin when it was 400 bucks. he just unloaded all of it recently. and bought a brand new 7 series.

Please DO NOT do that to yourself. You will be losing a lot of your money. I remember talking with a few analysts back in 2014 in my department and the consensus was…“not based on any fundamentals, no physical asset to back, etc. etc.” I believed all that until now. BTC is only getting more popular from here and other alt coins based on block chain tech. Very bad idea.

Bitcoin futures to launch in December? Usually you can short futures.
