After what has happened to FTX this week I now want to have everything on my ledger.
Self-custody is always meant to be in the cryptocurrency ecosystem.
According to Ledger supported cryptocurrencies information site, you can use a Ledger Live or MyHbarWallet, on MyHbarWallet you can just connect the wallet with your HW. Do note, MyHbarWallet only support Ledger Nano.
In case you have another device, the only option left is to use Ledger Live. It seems HBAR is fully supported on Ledge, for full references and a how-to guide, refer to https://support.ledger.com/hc/en-us/articles/360009833299?docs=true.
