if the hardware wallet company ledger goes out of business, what will happen to my crypto asset / private keys in ledger? if the hardware wallet company ledger goes out of business, what will happen to my crypto asset / private keys in ledger? I heard that the hardware wallet ledger is not open-source, so will the company get access to my private key? Will I be able to transfer my crypto elsewhere?
Your keys are stored securely on the hardware device itself.
If Ledger (or Trezor) goes out of business then their wallet client will also most likely not be supported anymore.
This isn’t that much of an issue. Other wallets have support for interacting with your hardware wallet, like Electrum for BTC, Electron Cash for BCH, and MyEtherWallet’s website for ETH.
If you also have your seed written down, you can import that seed into Electrum. This is more of a last resort move though.
