How Ledger can scam you even if they say that they will stop support all products? You should have backup in safe place, and with that backup you can get access to your coins with help of some other wallet.
Well said, my friend. As long as you have the words written down in a safe place you don't even need the physical wallet, and whether Ledger puts out any more updates is irrelevant to your coins.
The only cold storage option I'm 100% comfortable with is having the seed phrase from Electrum written down in a safe place. There is always the possibility of it getting stolen or destroyed, but at least it cannot be hacked. No doubt there are other methods which are safer, but a lot of those are just personal preference. Everything entails some risk.
