My Bitcoin address is: bc1qfyyy5wlgxweg5fs06skklfgv4hnsam0tt9wlmc
You should also provide a signed message so they can verify it.
Oh, nevermind then. I've deleted every bitcoin software/wallet I had.
The idea of the stacked address is to confirm ( when needed) that you still have control over the private key of that address. It is not a must to sign a message but it is recommended, that way you eliminate the chance to stake an address you don't own the private keys of even that you have control over the funds in it, like an exchange address.
Should sign a message with the address you want to prove ownership.
The post is quoted by some users, it is a kind of proof but not enough. The guy can not sign a message now but months or years later, if he want to prove his ownership with the account and with the address, he must sign a message from the address. Without a sign message from the same quoted address, it is not a proof of ownership.
If you have a paper wallet somewhere, and you don't want to mess with it until is really necessary (security reasons) I think it should be OK to stake only the address. You have control over the private keys but you don't want to mess around with importing them just to stake it. For me it's OK if you know what are you doing. Later on, when you really need to prove your identity, then you can take the risk to import the keys and sign a message.
Everyone should take it's own responsibility for their actions, we have already warred them, if they follow it's OK, if they think they have everything secured and it's no need, it OK either. As long as you don't stake an address you cannot sign a message from, it's fine.
This part is mostly for the newbies, to learn and know how to sign and verify messages, and to be sure they control the address.
