All this was discussed in the
Ledger Nano S Plus topic. You could have been reading that first, really...
So apparently I do not see this available in ledger website anymore. So this has been discontinued? How long ago did they stop selling it on ledger website?
Afaik it's not discontinued yet, meaning that for a while (at least the EU legal 2 years) they should still offer support for it.
Does this also mean anyone that has a nano ledger s would eventually need to get a nano ledger s plus or x in the future? I know lot of people from years back bought the nano ledger s and store their coins there. But is there any concern now that because this product is discontinued, it won't work later on in the future such as there won't be any firmware updates for it anymore?
Yes, sooner or later it will most probably get discontinued and if vulnerabilities are found, then using the old device will become unsafe.
At that point it will be recommended to buy another HW (from Ledger or not).
Do you recommend everyone with just a nano ledger s now buy another hardware wallet such as the nano s plus or the x and just input their seed phrase into the new hardware wallet and no longer use the nano ledger s anymore or there is absolutely no need for that now?
Now? No. Not yet, by far.
