The release of future ETH contracts may be suspended until the CFTC releases its review of the ETH currency

crypto currency enthusiasts thrived in June when the US Securities and Exchange Commission (SEC) removed what traders believed was a major obstacle to Ether's entry into futures markets.

The other CFTC softened some of this optimism Tuesday by noting that it still faces some fundamental problems with etherium, the third currency by market value.

The CFTC, the body that regulates derivatives, said in a statement it plans to look for general reactions to etherium so that it can better understand the similarities and differences of digital currency with bitcoin. The futures control committee has raised a number of questions about it for etherium.

Many traders concluded that the bourses would soon start offering futures contracts after William Henman, who runs the corporate finance department at the Securities and Exchange Commission, said six months ago that he did not believe the currency in its current form was securities and that it had jurisdiction over it . At the time, Chris Kuncanon, chairman of Cboe Markets, said the announcement had put a dent in the futures contracts for etherium.

The CFTC referred to Henman on Tuesday, saying his remarks conveyed only his personal views.
