ITs my first account I am selling so I have no clue with the signed message stuff.
The positive trust is from real life item deals.
EDIT.
Does not have green trust. (I had custom trust on..)
Its on Black Positive trust.
That means if you posted your BTC address anywhere in the forum 3 months or older than that and if you can verify that you can still access to that BTC address you posted
I never post my address on the forums.
DevtheDev can verify that I have sent him funds using the account.
He has also been notified I was selling my account so if he should receive any messages from it, it will not be me who is writing them.
