“Currently, the top four bitcoin exchanges by volume are located outside of the US, with the world’s leading exchange based in China. Less than 2% of worldwide bitcoin trading and real-time market making occurs within the US jurisdiction. All four of the world’s leading exchanges have demonstrated a capacity for serious, engaged banking relationships that would have been unobtainable in the United States. We have arrived at the point where the US jurisdiction must strategically evaluate a path going forward. Either they enable a climate that appeals to bitcoin exchanges and businesses or they maintain barriers that silently drive innovation in the space overseas.”
