1101 GMT - Bitcoin and ether could continue to trade in a narrow range due to uncertainty over U.S. cryptocurrency regulation, Mesta founder Sandeep Pyapali says in a note. The White House is expected to host a meeting Wednesday with cryptocurrency executives including from Ripple and Coinbase to discuss regulation. The meeting comes as the Clarity Act, which establishes a regulatory framework for digital assets, has been stuck in the Senate since June with a procedural vote delayed until September 15. "Until the regulatory fog clears, bitcoin and ether could remain range-bound, even if the macro data improves," Pyapali says. Bitcoin falls 0.3% to $64,344, according to LSEG. Ether rises 0.3% to $1,918.
