Most Influential 2021: Devin Finzer
OpenSea was most recently valued at $10 billion.

Devin Finzer is the co-founder and CEO of the world’s largest non-fungible token (NFT) platform, OpenSea. Finzer says his interest was sparked by the feline-themed token project, CryptoKitties, in 2017, the same year he started developing OpenSea as part of startup incubator Y Combinator. Sometimes called the “eBay for NFTs,” Finzer’s decentralized marketplace, run by a team of 20 and backed by venture firm Andreessen Horowitz (a16z), routinely sees daily volumes in excess of $100 million.
The firm was most recently valued at $10 billion, making it one of the largest crypto companies operating. There are questions of whether OpenSea will follow competitor platform, like Rarible, in issuing a governance token. The recently hired Chief Financial Officer Brian Roberts, who shepherded ride-hailing app Lyft through a public listing, has said “it would be foolish not to think about going public.”

KuCoin Hits Record Market Share as 2025 Volumes Outpace Crypto Market

KuCoin captured a record share of centralised exchange volume in 2025, with more than $1.25tn traded as its volumes grew faster than the wider crypto market.
What to know:
- KuCoin recorded over $1.25 trillion in total trading volume in 2025, equivalent to an average of roughly $114 billion per month, marking its strongest year on record.
- This performance translated into an all-time high share of centralised exchange volume, as KuCoin’s activity expanded faster than aggregate CEX volumes, which slowed during periods of lower market volatility.
- Spot and derivatives volumes were evenly split, each exceeding $500 billion for the year, signalling broad-based usage rather than reliance on a single product line.
- Altcoins accounted for the majority of trading activity, reinforcing KuCoin’s role as a primary liquidity venue beyond BTC and ETH at a time when majors saw more muted turnover.
- Even as overall crypto volumes softened mid-year, KuCoin maintained elevated baseline activity, indicating structurally higher user engagement rather than short-lived volume spikes.
