No, multisig can be done on Ledger as well. But it sketched me out when Ledger put out their firmware upgrade allowing you to opt in to a custodial seed phrase recovery service, meaning technically they could theoretically extract your seed phrase from the device. Then I listened to a podcast with NVK, one of the founders of Coinkite (you can follow him on here), learned more about the trust associated with hardware wallets, and decided I wanted the most hardcore thing possible to protect my keys. I’ll still be using the Ledger as an intermediary wallet, just don’t want to keep all my savings on there. The podcast I listened to was on Natalie Brunell’s Coin Stories podcast btw.
