Crypto exchange Bullish made a blockbuster Wall Street debut, with shares opening at $90, more than doubling its IPO price.

Bullish's shares were indicated to open more than 75% above their initial public offering price on Wednesday, signaling growing investor confidence in the sector and boosting prospects for future U.S.

Six years after raising $4.2 billion in the most lucrative sale of crypto tokens to date, digital currency entrepreneurs Brendan Blumer and Kokuei Yuan returned for another blockbuster public offering.
