Some people might not know these sites but I think you don't need to post this since a lot of gamblers here already know where to go. Another thing is that there are a lot of signature campaigns here on gambling sites, people could just click on it.
For me, it is alright to be posted here. There are many people who are newbies here and still exploring about cryptocurrency and to earn money or cryptos in different ways. It will serve as a guide for those newbies who wants to start gambling. But not all people here wants casino for their gambling, others want to bet on sports or esports.
