I don't realy think that it will have a strong influence on bitcoin. I see to musch risk in BTC futures trading and I don't belive that it will be popular. I can hardly see traditional investors buying this type of futures just because BTC is too unpredictable for them. In general the bitcoin futures look more like a new type of gambling rather than an investment and I wouldn't expect any large flow of capital.
Any investment is a sort of gambling to begin with,you really never know what the future holds,i am really interested to see the options of having a futures market in bitcoin,but i have not thought about the way it is mentioned in the article,i do expect big institutionalized manipulation in the price of bitcoin when the future market starts and how to evaluate those situations is to be seen.
