According to @EmberCN, Vitalik Buterin transferred 6.307 million STRK (about $1.09 million) to the Methuselah Foundation wallet roughly 10 minutes before the post, and Methuselah is selling these STRK into ETH; the transfer address is visible via Arkham at intel.arkm.com/explorer/address/0x220866B1A2219f40e72f5c628B65D54268cA3A9D (source: @EmberCN; source: Arkham). The STRK were unlocked yesterday, and Buterin’s 2018 StarkNet seed allocation totals 25.356 million STRK, with 16.951 million STRK (about $2.91 million) still locked (source: @EmberCN). Based on these figures from @EmberCN, the 6.307 million STRK moved equals roughly 24.9% of his total allocation and about 75% of the currently unlocked balance, which traders can verify via the cited Arkham address (source: @EmberCN; source: Arkham).
