Coinbase Global, Inc.
A platform for buying, selling, and storing digital currencies like Bitcoin and Ethereum, Coinbase runs one of the world's largest cryptocurrency exchanges. It was founded in 2012 by Brian Armstrong, a former Airbnb software engineer who built the early version of the company as a late-night side project, and Fred Ehrsam. The name comes from the "coinbase transaction" in Bitcoin — the technical term for the first transaction in a block that creates new coins.
Estimated from filings — the split-adjusted price range over the quarters each manager built the position. A range, not a fill price; 13F reports a quarter-end snapshot, not a trade date.
