Shares of Coinbase Global Inc. were traded at an average price of about 350 USD each at a private auction held by Nasdaq, giving the San Francisco based crypto currency exchange a total valuation of about 90 billion USD, before the company goes public. The Nasdaq Private Market auction ended last Thursday and is probably the last chance for investors to trade Coinbase stocks before its public listing, which is expected to go ahead in the end of March. In the beginning of the auction some Coinbase shares were traded at a price above 375 USD, which would have given the company a total valuation exceeding 100 USD.
