Yes, bitcointalk gambling section does provide us this opportunity so that we can know about the gambling site services through the comments and feedback provided by the gamblers here but again not all sites have their ANN threads here. As an example, you will not find any complaints from Duelbits site and it is safe to play there. Similarly, i usually bet on stake.com without any issues.
Bitcointalk is the biggest forum in cryptocurrency and one of the oldest one which is still actively nowadays.
Gambling industry adapts so well to blockchain development and crypto-accepted casinos surely find this forum as one of the best places to advertise their casinos. They can choose either signature campaign, contests (art, wager ...) events, ban ads (that was stopped months ago by theymos). With many casinos like Duelbits run their advertisements here, I am sure they actually receive positive results from their money.
However, there are sites like 1xbit that are scamming people but it's strange that people still gamble on that site despite reading the negative views about that site. So sometimes it is the gambler's fault if he still wants to take risks and gamble at an untrusted scam site.
I would like to inform you and others that it is the announcement thread of Duelbits.com casino, not the one of 1xbit casino. Hence, I would prefer people who join discussions here, stop mentioning about 1xbit as well as other casinos in this announcement thread.
If anyone has issue with 1xbit, let's post it in their ANN thread or open an scam accusation topic about them. Please keep discussion here on topic, about Duelbits.
