I sold my hero member account for 1 btc before 2 years but the fact is at that time the price of bitcoins was too low so I couldn't enjoy that profits as it was spent very quickly on my basic stuffs.
Wow, today this would be very big sum and you would earned a lot. Still, it's a big amount for the account
But nowdays I think that account prices have fallen significantly and there is no use of selling account. There are also people who are farming accounts, what I find unfair and dishonest.
