They have around 100M registered users, so approximately 1 employee for every 100k users seems reasonable.
On chain, there are not more than 100k users across chains daily. Real users across all EVM chains is probably around 20k/day. Major airdrops like Optimism and Arbitrum went out to like 600k wallets (and most have multiple wallets). OpenSea has like a few thousand daily active users.
Which makes you wonder - all these billions in funding for serving just…100k real users? Because if its not onchain, it might as well be a database.
