I setup my ledger nano s properly and transferred my Ripple to ledger nano. Now I want to reset my ledger nano and generate new seed. I have transferred Ripple to some other exchange to reset my ledger but last 20 ripple can't be transferred as it is required for any ripple account. Once I will reset my device, can I use the same ripple wallet so that my 20 ripples won't be lost or I will have to forget these 20 ripples in terms of resetting my ledger nano? Is there any other way to save these 20 ripples?
