Dont throw away or distroy your Ledger walllet

Use it as a part of your multisig setup on desktop wallet like Sparrow

If you use your own node (preffrred) or public node selected by Sparow then people at Ledger can not see your transactions

Even if they can see your multisig part seed they can noot steal your bitcoin

For that they need your xpub and and one or more multisig seeds
