A short video that looks at unsafe Bitcoin wallets that were likely created using low numbers of dicerolls leading to poor wallet BIP39 seed security, making it easy for scammers to access the private keys. I also look at how many folk lost funds doing this and which hardware/software could have been used to create these insecure wallets in the first place. It also include a demo of how this can still happen with Coldcard Mk4, even running the latest firmware.
