Yes, they do. When you win either $20 or $200 of Bitcoin on a free roll you get an email telling you that if you post in that thread then your account will be credited with a bonus of $5 of Bitcoin. That's why there are so many newbie accounts that post, most of the freebitco.in customers are not already on this forum.
That's actually pretty interesting. I wonder if that ends up paying off for them in the long-run.
Hey that's not correct. I had won 9999 and I didn't get such a mail. All I got a mail saying congratulations you have won 9999 jackpot 20$. There was no such mention of, 5$ being awarded. Can you post proof of this cause this would not be fair to me and other's who didn't receive such a mail. I'll recheck it, cause i had posted here but my account never got credited for the extra 5$ so I feel there is a misunderstanding here.
I guess someone trying to spread fud about freebitco.in here's the proof there's no incentives maybe for this they'll give me btc directly to wallet lol.

Big wins thread was created on April, 1st 2017. You won $20 in 2016, so I suppose this reward for big free roll winners wasn't available yet at that time.
