As crypto prices remain fairly volatile and without a clear trend, a group of lawmakers from the U.S. Congress has recently addressed the Securities and Exchange Commission (SEC), asking it to provide more regulatory clarity for the crypto industry. Specifically, more than a dozen congressmen have asked SEC Chairman Jay Clayton to provide criteria for identifying digital tokens as securities.

Anthony Pompliano, founder and partner at Morgan Creek Digital Assets, has summarized the main crypto industry events of the week in his tweet September 30.

The industry expert has highlighted such events as the crypto mining giant Bitmain filing for an initial public offering (IPO) on the Hong Kong Stock Exchange, the partial reversal of Google’s crypto ad ban, and the upcoming launch of a stable cryptocurrency (stablecoin) by the peer-to-peer payments company Circle.
