After Coldcard, 15 Billion Dollars in Bitcoin Seek Refuge

The Coldcard hack increasingly resembles a crypto news item. Except the real story isn’t hidden in the 130 million stolen… It’s hidden in the 15 billion dollars that fled in bitcoin transfers.

In Brief

Bitcoin: 15 Billion Dollars Gone to Safety After the Coldcard Heist

When hackers were cracking Coldcard bitcoin wallets one by one, something else was happening… Something much larger… And in silence. Casa’s CEO, Nick Neuman, revealed a colossal movement of 233,000 BTC, about 15 billion dollars, which left wallets held for over 155 days. This category is watched by analysts as a barometer for serious, patient investors—not ones who panic over a tweet. The funniest part is that some of this volume didn’t even come from Coldcard users.

But Ledger and Trezor holders took advantage of the shock to switch to multisig, fearing they might be next on the list. For every dollar stolen, a hundred dollars were cautiously moved, and Glassnode confirms the magnitude of this movement. Long-term holders’ reserves dropped from nearly 15 million bitcoins to about 14.7 million. The largest weekly decline since December 2024. For Neuman, this proves that distributed self-custody works like an immune system, not a weakness.
