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 !
All those people who are selling their accounts are lazy people who cannot make good post to be accepted in Btc service signature compaign. It's not worth how old your account is but your rank will be considered because most of buyer only buy accounts because of joining signature compaign purpose. I think if someone as a full member just join bounties signature, its more profitable than selling account cheaply .
This is also another point worth mentioning. If you cannot grow your account, buying a high ranked account won't help as you will not get merits because you won't be posting anything constructive. Also, these days, only being high rank account does not grantee you a spot in signature campaigns, you need to be good in writing too.
I continue the btt account, so it is more valuable than anything.
Yeah, until you sell it and it get noticed / flagged, the most valuable thing becomes the most useless thing especially for the buyer of that account.
