Wait, but was the nano ledger S price 59.99 before the 30% discount?
Yes, it was, so $42 after discount.
You say there was a 50% discount in 2018 but this was when the ledger was selling for over 129 dollars right?
The price at the time was $100, so $50 after discount.
Btw do you have 1 nano ledger s and one X?
No. I have several S models but no X models. I don't care for most altcoins so have no need for the larger storage, and have a phone which is compatible with the Nano S, so no need for Bluetooth either. As nice as it would be to have the latest model, it's not worth the price for me for features I don't need and wouldn't use.
If you only own just one nano ledger s, would you say its good idea to buy a backup nano ledger s now since the price is already low?
I like having backup wallets in addition to having my seed backed up on paper, and store them in different locations. Having said that, the more wallets you have, the more chance of one of them being discovered or stolen.
Also are there ppl that buy 2 nano s and keep like half their crypto in each hardwallet wallet... or is that bad idea?
As HCP has said, find out what works for you. Some people duplicate the same wallet across different devices, some split their coins across multiple wallets, some use multiple passphrases, some use multisig, some use a combination of all of these, etc.
