Im sorry to have to repeat to you, nowadays have any account above full member without staked adress= hacked accounts, soo no one will deal with you with such account without any adress. This is a security measure to protect owners from hackers, and im pretty sure you as seller should know already those, but looks like you arent an active member of this forum.
Lol you had to jump into your 2nd or 3rd account in order to re-write the same thing?
You have no idea what your talking about, so many accounts were sold without signed message. Signed message is specially for those who are well incrusted into bitcoin and its environement and believe their account is as important as their identity. This is the internet and I never had enough bitocins in my possession to feel the need to sign any message. Once again get lost your just wasting your time with your multiple account posting.
