I saw Hero/Senior accounts going real cheap lately. Maybe that will continue. But Da Dice and 7BitCasino have new high-paying campaigns for Hero Members, so sellers may start upping their prices. Just my two cents on the current state of the market. 
That's what I see. ^__^
Not selling right now until demand picks up.
Who said they will pick up? I think if they were going to they would have already. Market is flooded with accounts but there's still decent paying deals around just people don't wanna pay over the odds for accounts.
