Aren't you going to address the concerns above? If you don't,you won't be getting any buyers whatsoever.
Until you have a signed message, I'll be doubting your true ownership of the account.
I`m selling my acc at 0.16 BTC coz I can not provide signed message (due to the fact that I never used satoshi wallet and I trade only altcoins). If you are looking signed message Sr Member accounts, feel free to buy them at 0.30+ BTC on this forum.
If my acc is not sold till the end of the month,
I`ll keep it, sign it, upgrade it to the Hero Member and sell it at higher price. This is the best way you can do for now. You can only get little amount if you have no signed message. One more thing, saying this things looks like you are in a hurry selling this account. Are you sure this isn't hacked?
