AFAIK, the data breach at Ledger concerned their customer database and had nothing to do with their products themselves.
The beauty of Ledger (and Trezor, if I‘m not mistaken) is that you can use it to store a spectrum of crypto currencies on one device. Coldcard is only for BTC AFAIK, so it’s only partially a good alternative. What would you suggest as a true alternative to Ledger with even fewer drawbacks?
