I have a few bitcoin savings in Ledger Nano s which I never open since 2 years ago, and I never connect with Live applications except only connect with Electrum. So, does my ledger have an impact or effect? I don't want to try it and don't intend to open it now, because I save it for the next 10-15 years, now, I have doubts if is it really safe to continue it or if I must move my balance to another hardware wallet, Please give me instruction what the best, I'm still young and only have bitcoin as my current investment for future.
