I think if you want your assets are safe, just buy a hardware wallet. That is safe wallet you can use. Like nano ledger or trezor is good wallet, I suggest you buy it in new condition.
Do not buy a used hardware wallet. You have no idea what the previous owner potentially did to it and you risk losing your funds. Don't skimp on security!
Is that so? So are you saying that hardware wallet is not safe? If this would be the case then no one will buy hardware wallet anymore. I think there is a way on how to deal with this and better ask for support. I, personally have been planning to buy hardware wallet so i am interested on this.
