I just noticed that people were selling their bitcointalk account here
And I am wondering how much mine would be worth
It is almost 10 years old !
You are a Sr member and your account ma be worth a lot but as soon as you will sell it or even try to sell it, it will be of no value, useless.
Account sales are not encouraged and i would suggest you never sell or think of selling your account. If you do not want to use it, keep it with you. I can't stress it more, DO NOT SELL YOUR ACCOUNT.
