#BNBBreaksATH It's not just bitcoin (BTC-USD) that corporate treasuries are buying. A handful of firms are scooping up ethereum — or its native token, ether (ETH-USD) — as a way to gain exposure to the tech infrastructure behind decentralized finance and digital assets.

So far, the companies taking this approach are mainly smaller names in the crypto world, such as BitMine Immersion Technologies (BMNR), chaired by Fundstrat's Tom Lee. One larger player — Coinbase Global (COIN), the parent company of trading network Coinbase — has more than $440 million in holdings, according to crypto and investment tracker CoinGecko
