There was something like cloudbet. A lot of scams. Isn't that another?
Hm please elaborate why do you think freebitcoin may be a scam? The site is one of the oldest Bitcoin-related sites out there. Thousands of people use it (or one of its competitors) on a daily basis, including me. I am sure we would know already if they would scam its users.
why are you promoting something you're not sure?
I don't promote it, OP asked for sites offering esports bet, I gave him the hint that freebitco.in may have listed such bets.
Bitcoin and reliable feedback? Without a third partner escrow, it makes no sense
He was talking about reliable feedback about online casinos I think. A good start would be the site-related threads here at BTT. Every major and well known site has its own thread, you may ask questions and usually get answers in no time, sometimes even from the guys running the site.
