I have both the Trezor and the Ledger hardware wallets, but because Pmalek firmly emphasized that Ledger's firmware is not open source, and that we would never know if their hardware wallets are actually safe until they show their firmware's code to the world, he said Ledger users are taking a massive risk.

My Ledger is still brand new/never used since November 30, 2024. I said I'll use it for small amounts of Bitcoin, but I never did.
