A Sotheby's co-branded Ledger Nano X is what you didn't know you needed, according to Sotheby's, at least.

The world's most famous auction house teamed up with Ledger to give buyers of 'premium digital art' auction lots in 2024 a Ledger cold wallet.

Roughly translated, it means you'll get one of these for free when you buy an expensive NFT from Sotheby's.

Also, and they don't advertise this part, you can 100 percent expect these things to surface in the pre-owned market on eBay for a lot of cash. Resellers and flippers never sleep.
