Plenty of people buying now before the fork for the BT Gold and afterwards a downfall for all people selling the BTC again. Either to reinvest in BTC afterwards or in other altcoin.
that is the only reason why people hold bitcoin, they want to get the bitcoin gold that can be for free from the second hard fork, and I think it will invite the risk because very high bitcoin volume is circulating in all exchange, I'm afraid if bitcoin will disappear and be replaced with gold bitcoin
