Disgraced crypto founder says he’s not on the run. But no one knows where he is.

The person most closely associated with last spring’s crypto crash appears to be on the run after an arrest warrant was issued for him — and investigators have asked for Interpol’s help to track him down.

Do Kwon, the South Korean developer of the TerraUSD and Luna cryptocurrencies, is believed to have been in Singapore since at least the spring, when those coins lost nearly all of their value. But Singapore authorities said this weekend he is no longer there, and South Korean investigators have reportedly asked Interpol to issue a “red notice” that would allow officers in member countries to provisionally arrest Kwon pending extradition if they find him.
