Coinbase, the digital currency exchange service, is going public with an initial public offering, and is expected to net big gains thanks to a cryptocurrency boom. Co-founder and CEO Brian Armstrong is a multibillionaire as a result of the listing. How much of one is still uncertain; ahead of going public, Coinbase is valued at more than $100B, meaning Armstrong’s stake in the company is anywhere from $7B to $15B. That puts him among the top 500 richest people in the world, according to Bloomberg, which tracks net-worth rankings. The company was founded in 2012.
