Bitcoin ETFs gain case after $88.6M drain

• Galaxy Research linked 1,367.05 Bitcoin worth US$88.6 million to suspected drains from vulnerable Coldcard wallets.
• The research identified 4,585 affected addresses across three waves, although US$88.6 million remains an estimated observed figure.
• Bloomberg analyst Eric Balchunas said the incident strengthens the case for ETFs by removing individual seed-management responsibilities.

Galaxy Research linked 1,367.05 Bitcoin (CRYPTO) worth US$88.6 million across 4,585 addresses to suspected Coldcard wallet drains.

The research identified three draining waves, although Galaxy described US$88.6 million as the estimated observed size rather than a confirmed loss.

“Yes, an ETF fixes this,” said Bloomberg Intelligence Senior ETF Analyst Eric Balchunas.

BlackRock's iShares Bitcoin Trust ETF (NASDAQ) held US$46.52 billion in net assets as of 31 July and charges a 0.25% sponsor fee.

Balchunas argued ETFs remove seed-management risks for investors, although no evidence shows the Coldcard incident directly increased ETF demand.

Spot Bitcoin ETFs provide Bitcoin price exposure through regulated funds, shifting private-key management from individual investors to institutional custodians.

Coinbase Custody holds IBIT's private keys in segregated cold-storage wallets, meaning custody risks remain but are managed through institutional infrastructure.

At the time of reporting, Bitcoin price was $63,481.80.
