OneKey CEO warns North Korean hackers may target BlackRock’s bitcoin ETF

OneKey founder and CEO Yishi Wang warned that North Korean hackers, after targeting Binance, could next go after BlackRock's IBIT, the largest bitcoin ETF with nearly $63 billion in BTC custodied solely by Coinbase. The claim is an executive's speculation rather than a confirmed breach, but it highlights concentration risk around a single custodian holding a huge share of ETF bitcoin. Traders may watch Coinbase custody and IBIT flows for any sign of stress, though no incident has been reported.
