It appears there might be a new notice from Bitfinex out that refers to legal challenges with the US government, specificlaly related to the existence of ICO tokens.
The exchange explained that the decision follows a recent investigation by the U.S. Securities and Exchange Commission (SEC) on how tokens issued by way of an initial coin offering (ICO) may be considered securities.
I wasn't aware of specific investigations into ICOs...anyone else heard of such investigations?
