Just looked at the on-chain data and it's wild how concentrated ETH holdings actually are. Over 60% is locked in staking contracts, but what really caught my eye is the individual holder breakdown. Vitalik Buterin net worth in ETH alone is sitting around $754 million with his 240,000 tokens - making him the largest accessible holder. But there's this crazy story about Rain Lohmus, an Estonian banker who bought 250,000 ETH back in 2014 for like $75k when it was $0.30. His ETH is worth way more now, but here's the kicker - he lost the private keys. So technically he's the biggest holder by amount, but completely locked out of his own fortune. Vitalik Buterin net worth could look different if you count inaccessible holdings, but realistically he's sitting pretty as the top accessible whale. The whole thing is a reminder of how brutal losing keys can be in this space - that guy's watching his $1.2B+ just sitting there on the blockchain, untouchable.
