Max Galka(@galka_max):Several Coldcard honeypots were cracked by thieves and their BTC was swept to fresh, single-use addresses. Why is this concerning? Because on the blockchain, transfers like these are indistinguishable from Coldcard owners rescuing their coins, so these cases would likely not be counted in the current loss estimates (~$116m). So how much bigger could the actual loss be? How many other transfers match this profile? Answer: ~36k transactions totaling ~$2.1bn of BTC. These transfers are equally consistent with an owner rescue or a theft, and nobody can determine which. The actual Coldcard loss could be *much* larger than current estimates. See how these numbers were determined:
