Coldcard and the blow to crypto confidence: massive drains shake the market

Security was the theme of the week in the crypto ecosystem. A series of attacks and waves of drains on Coldcard hardware wallets — considered among the most secure on the market — caused multi-million losses and concern among retail investors.

The paradox of the moment

While confidence in physical wallets cracked, the market offered a story of hope: a solo miner managed to mine Bitcoin block 960,804, pocketing a reward of approximately 3.157 BTC (about US$199,300). A statistically improbable stroke of luck: most mining is dominated by large pools.

The practical lesson

The Coldcard case reminds us that no device is infallible: hardware wallets are protected by seed phrases that must never be digitized, and security depends as much on the device as on user habits. Verifying addresses, updating firmware and distrusting miracle offers remain the golden rules.

The key figure

US$199,300. The solo miner’s reward in a market that, at the same time, saw confidence in its digital vaults waver.
