BlackRock sent 861 BTC and 44,691 ETH to Coinbase in two deposits worth about $173 million. The move drew attention because Coinbase is custodian for BlackRock's spot Bitcoin ETF (IBIT) and spot Ethereum ETF (ETHA), and an on-chain deposit alone does not confirm selling. Market watchers are now focused on whether the assets remain in custody or later move to trading-linked wallets.

On May 12, Ash Crypto highlighted copper's May intramonth high of $6.62 and a close at $6.54, arguing past cycles saw altcoins react with a lag while the "Others" altcoin market cap stayed near $200 billion. Michaël van de Poppe instead focuses on the copper/gold ratio, saying its early-2026 turn after a roughly five-year downtrend tracks ETH/BTC closely. Both readings suggest altcoins have not yet responded, but they differ on whether nominal copper strength or the ratio-based risk signal is the cleaner trigger.
