for your green rep that you mentioned, how many #s does it show.

Trust # / +???

is price non-negotiable?

No problem, the reason it is 'so important' to have a signed message posted by the account a long time ago is to prove that the account is owned by you and that you transfer it to the buyer upon purchase. Have you posted a btc address from the account in your 1 and a half years that you still control the address? Here is a brilliant walk threw how to sign a message https://bitcointalk.org/index.php?topic=990345.0 . A signed message on a hero account sale is a must. PS 1year.6months here and you don't know how to sign a message or you don't know much about crypto, give you benefit of the doubt but that does not sound right to me.

A lot of accounts have higher trust rating now, how many different positive trust feedbacks does it have? How long ago can you sign a message from associated with this account as you have not stated and that is a big deal. I have to give you a heads up for a newly Hero account you are not getting nowhere near 3btc! Sorry to break it to you, you will be very very lucky to get 1btc
