Account selling is legal but it is frowned upon. There was a time people would do it and it was not a big deal. Now that btc has a lot of value people do not like it to be done.
I have been offered over $10,000 to sell my account.
I would never consider selling it .
As for the poster here maybe he was scammed maybe not I don't know.
Why should selling of reputation actually be allowed on the forum? Because, in selling of account, the individual is also selling their reputation which is something that can’t be transferred or granted a person but rather earned. If account selling should be allowed to be a thing, then it should come with some written statement, maybe as a trust rating or a warning on the account by the individuals involved in this trade to let the public know that, it’s changed hands.
$10k is huge but, you hold your reputation a lot higher than that, it speaks of your charisma.
