>"Coinbase, the American cryptocurrency exchange that is planning for an initial public offering (IPO), could be valued at $28 billion, according to research company Messari. This valuation estimation came hours after the California-headquartered company announced the submission of a draft registration statement on Form S-1 with the US securities market regulator, eying for a public listing. Mesarri came up with the valuation after evaluating the exchange’s all business vertices that include trading, custody, and debit cards. “Recently the company shuffled its board to include venture capitalist Marc Andreessen and Google veteran Gokul Rajaram along with former Cisco CFO Kelly Kramer in what appears to be final preparations for an offering that could see the company valued at $28 billion,” Messari wrote."
