CFTC seeks further information on Ether

The Commodity Futures Trading Commission said on Tuesday it is seeking public feedback on virtual currencies, namely Ether, the currency that runs on the ethereum network.

Ether rose in popularity in late 2017 as crypto ventures issued the cryptocurrency when conducting initial coin offerings, or ICOs, an alternative crowdfunding tool. However, after rising above $1,400, the price of Ether has plummeted below $100 amid speculation cash-strapped crypto ventures are having to sell their Ether holdings to raise cash.

“The RFI [Request For Information] also seeks to understand similarities and distinctions between Ether and bitcoin, as well as Ether-specific opportunities, challenges, and risks,” the CFTC said.
