Citadel's billionaire founder and CEO Ken Griffin has weighed in on FTX's speculator collapse, calling on American regulators to cooperate with each other to better supervise the crypto industry.

"The turf war by American regulators has got to end. It's just preposterous," Griffin said Tuesday at the Bloomberg New Economy Forum in Singapore. "Without naming the agencies, they all dance around who owns what. The bottom line is American investors have really gotten hurt to the tune of hundreds of billions of dollars in declining market cap of crypto over the last two years. That really strikes at the entire core essence of what investor protection is all about."
