#coldcard #hack #rng #sweep #privacy
I have had another thought I want to share with whoever reads my thoughts.
So we all know that the Coldcard addresses created by these deterministic private keys are being swept. The MK3 devices are already done being swept. And attackers have moved on to the slightly harder MK4 devices etc.
I have a lot to say about this inevitable process but for this post...
I know many of you are very adamant about privacy and may have even done utxo coin control and tried to acquire non KYC coins and so on...
Well, you might as well make peace with the fact that your UTXOs are eventually going to be known even if you have already moved your coins to another wallet.
Because the attackers will eventually find your wallet and see your history and all the UTXOs and everywhere they went, etc. So this stuff's going to all be cataloged and kept by black hats, white hats, and the rest.
Once everything is settled and the smoke is cleared, you can work on anonymizing your UTXOs however you choose to do that in the future.
