I never even mentioned a Ledger wallet. I did own one, but I dont use that shitty piece of hardware ever again. But what you said is not true for the vast majority of hardware wallets. I dont know where you got the idea that I was talking about Ledger devices? I suggest you research a little more about how hardware wallets work.
Bitcoin only wallets maybe, others not. In most cases it must be connected to a device that is online and other software.
We must be careful with the logic that we use, otherwise we could consider mobile wallets as offline wallets as long as we keep them then disconnected from the internet. Lol
Thats literally the definition of the word "offline". In technical contexts, it means disconnected from the network, in this case the Internet. So yes, if you have a wallet installed on a device that is disconnected from the network, that is by definition an "offline wallet." Im not arguing here that this always makes it a good option for cold storage. It depends on the setup.
No it is not. For a wallet to be an offline wallet it must be offline all the time. It can't be offline some of the time. If it could, then where do you draw the line? 10% offline time is enough? 20%? 50%? Either it is an offline or online wallet it is a binary choice.
Hardware wallets are cold wallets and with cold wallets, you sign a transaction when your wallet private key is not exposed to the Internet, and your wallet (cold wallet) is not online.
Nope that is not correct. We have clarified here. You connect a closed source device to another that is connected to the internet. That can never be a cold wallet.
