in the original topic.. it was casinotester that started that other topic.

his game is he likes to BUY old addresses.

general opinion is he wanted people to publish so that he can seek them out to buy those private keys from them..

so now he is trying to be subtle about converting them into some NFT thing. which basically means he then wants to sell those privkeys to someone else..

in short he is a private key broker

..
here is the problem selling a private key is the same as giving more people access to the private key.

NFT dont work that way

the (hash) of an NFT is transfered to different peoples key. so that no one has access to the private keys thus there is no spread of key holders.

..
what casino wants to do however. is sell you a private key.. knowing he gets to keep the key to sell it again to someone else so that more people all use the key and no one really owns the it out-right because too many people have access to sign with it

as for the other usernam "one signature" i believe that its an alt account of casino tester. and he bought a private key previously and is just showing off a signature to spark social drama/gossip for free advertising in the hope others would have also signed and published so he can sales call on those people
