my question is about like a online service that creates cold storage addresses
like a user press a button and a cold storage address is created on which he can sent its bitcoin and recover all the security stuff (private key ie)
Let's imagine for a moment that a website claimed to be able to create a private key offline and display it's public address for you online... How would you prove that this website is indeed doing that and not just creating a key pair that's live on their server?
I think if you store it on cloudbox or othe cloud storage,it will work as cold storage although not in strict sense.By the way why would you like to keep it online,and whats wrong in keeping it with your online wallet if you want to keep it online?
Same as a few posts above, it would cease to be cold the moment you put it online, no matter how encrypted and secure it is.
Nothing wrong in having an online wallet, but we're discussing cold wallets.
