The chairman of the largest American electronic broker "Interactive Brokers" published on the whole page of the The Wall Street Journal a warning on the the dangers that bitcoin futures could present to traditional capital markets. This is reported by the Business Insider.
Chairman of Interactive Brokers Thomas Peterffy addressed his message to the CFTC Chairman Christopher Giancarlo expressing his concern over the plans of the Chicago Mercantile Exchange (CME Group) for bitcoin futures, which the are planed to launch in December this year.
This letter is to request [the CFTC] require any clearing organization that wishes to clear any cryptocurrency or derivative do so in a separate clearing system isolated from other products. Cryptocurrencies do not have a mature, regulated and tested underlying market. The products and their markets have existed for fewer than 10 years and bear little if any relationship to any economic circumstance or reality in the world.

Also, according to Peterffy, the "unbridled volatility" of bitcoin can be dangerous for other futures contracts on the market, and therefore the clearing of such derivatives should be carried out by the relevant organizations in isolation from other derivative financial instruments. Otherwise, the head of Interactive Brokers believes, bitcoin futures as a result can "destabilize the real economy."
