Cryptocurrency broker Coinbase could leave the US — where it is one of the few large publicly traded digital asset businesses — if regulatory clarity for the sector doesn't improve, its CEO said.

"The US has the potential to be an important market for crypto, but right now we are not seeing that regulatory clarity that we need," Coinbase CEO Brian Armstrong said in remarks at a fintech conference in London, CoinDesk reported on 18 April. "I think in a number of years if we don't see that regulatory clarity emerge in the US we may have to consider investing more elsewhere in the world... Anything is on the table, including relocating or whatever is necessary."
