What a coinsidence that all the "interested" members are noobs without any history and all of them wants to trade through TG.
Who will be such an idiot as to buy a used wallet address with shared private keys just because it's old? There isn't any value in it whatsoever. Unless the purpose of buying it is for a possible scam attempt. That's the only thing that can explain this "demand" from such "members" for such a useless thing.
