Could you please clarify if it's possible to securely store Mina coins on a Ledger hardware wallet? I've heard Ledger is a trusted brand in cryptocurrency security, and I'm looking for a reliable solution to safeguard my Mina holdings. Does Mina have direct support for Ledger wallets, or are there any known compatibility issues? Also, are there any specific steps or considerations I should be aware of when attempting to integrate Mina with a Ledger device? Your insights would be greatly appreciated.
