Odaily News Cryptocurrency exchange Coinbase said it is stepping up grassroots advocacy activities to promote legislation aimed at providing clear supervision for the encryption industry. A U.S. congressional committee advanced a cryptocurrency bill in July that would define when cryptocurrencies are securities or commodities. The industry wants a full vote on the bill in the U.S. House of Representatives. Coinbase will launch a comprehensive paid media campaign on Tuesday, including ads in Washington, D.C., and a call on cryptocurrency users on its platform to contact members of Congress and demand they pass cryptocurrency legislation. Coinbase is also organizing a “fly-in” event on September 27 that will bring executives and developers from about 35 cryptocurrency companies to meet with congressional staff and lawmakers. (Reuters)
