Lol.. That's simply not true. After I create a wallet. I back it up and then verify it. Then I wipe it. You can hack something that isn't there lol. But that's just one of many deterrents. I also use a high entropy passphrase\password. Which Trezor does not store. Even if I didn't wipe the device. The seed phrase is useless without the passphrase\password. With Coldcard you have to trust not one but two closed source elements. Do you really want to trust you life savings to that..😐
