I made some money on BTCC.B and GBTC , but have since had a change of heart on BTC. BTC is in no way comparable to gold, the utlimate currency for 6000 years. BTC has no real inherent value. The whole crytpocurrency space is a joke. If they ever do become successful, they'll get banned like in China and India. I see much more downside. Crytopcurrencies = Tulipmania
Gold is the original crazy-mad tulipmania cryptocurrency. How much energy has been expended (and lives lost) to dig it up, only to "bury" it in another hole, aka bank lock box or home safe.
