Is Ledger Nano X the best crypto wallet (in terms of most secure and easy use for many coins)? I find that the seed phrase generated is potentially very troubling for two reasons: (1) If other people spot the seed phrase, they can take away all the coins. How do you keep the seed phrase long term? (2) I read that "generally a seed phrase only works with the same wallet software that created it".  What if that software - Ledger Live is no longer available or workable in the future? Thanks for any relevant info.

People are paying very high premium buying bitcoin and ether in Grayscale's Fund - GBT and Ethe. I guess an important reason is that it is too difficult or too much trouble to keep and manage private keys themselves.
