Ethereum co-founder Vitalik Buterin has gone on a shitcoin selling spree, exchanging nearly $700,000 worth of tokens previously airdropped to him for Ether (

While some within the cryptocurrency community shared their frustration at Buterin’s decision to sell considering the outsized effect it had on the tokens, others suggested it was motivated by the tax implications of receiving airdrops, which are subject to income tax in most countries.

Buterin confirmed he owned the wallet in a 2018 tweet after he was accused of hoarding 75% of the supply of Ether with fellow Ethereum co-founder Joe Lubin during the token’s pre-mining sale.
