The institutions are creating the options market infrastructure for bitcoin so that they can control and manipulate the price. Just like they do with gold and silver markets. Also with high frequency trading applied to the blockchain the institutions will be able to fleece the little guys. Just my opinion but I believe generally that the mainstream legitimization equals control. The price will go up but limits will be set by those big players that can issue billions in "paper" bitcoin like they do with silver. Nothing can Stop the blockchain but it can be controlled. Just look at the trading shenanigans going on at Bitfinex recently before the split. That price manipulation was done without options trading and a tiny fraction of the money and hypothecation that will eventually come in to the BTC market. Being accepted into the club is great being subjected to the status quo not so great!
