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 !
Selling or buying a bitcointalk account is not a smart choice and for me a bitcointalk account is priceless because with a bitcointalk account you can generate coffers of profit by joining signatures. Likewise, if buying a bitcointalk account is very risky, if you get caught by DT, you will be given a negative trust tag.
Even if you are busy with real life, it would be better if you don't have time to open the forum, it's better if you leave your account alone because one day you will need the account again. If there is an intention to sell an account, remember when you created and built the account with great difficulty.
