Arkham, an onchain intelligence firm, disclosed on X social media platform that Blackrock's IBIT Bitcoin addresses received over $20,000 worth of Runes protocol tokens. These tokens, totaling 1,887,240 RSIC•GENESIS•RUNE, were airdropped at the beginning of the week. Each RSIC token is valued at 16.2 satoshis or $0.01, with a total market cap of around $220.14 million. Arkham revealed that Blackrock's wallets unintentionally acquired four Ordinal inscriptions, resulting in the airdrop. The RSIC tokens originated from a Coinbase Prime Hot Wallet and were initially airdropped to Swissborg. This revelation comes after Ark Invest's ARKB ETF was found in possession of a 'Bitcoin Puppet' NFT, and Blackrock also held a 'Speculum Aeternum' Ordinal inscription valued at $2,565.75.
