I check " Show unread posts since last visit." and 80% there is advertising some gambling or bets services , does it so popular here ?
For me, the reason is because bitcointalk is home of high rollers. This recent casinos who advertise or running signature campaigns here is trying their luck to got some high roller to play on their platform. They know this forum is where serious players gather, so it's the best place to attract people who like to bet big.
Yes, I agree. There are people with thousands of bitcoins that they gamble hundreds of bitcoins so casinos are trying to reach out to them. Doesn't mean every casino will get them, but the casinos that tries the hardest do. You know how we know this?
Stake, the casino, started all here. They were primedice, one of the earliest dice games in the world of crypto, lost 2000+ btc to hufflepuff, and still kept going, then lost 40 million a year ago or so, still kept going, they are now so big, they sponsor formula cars, football teams, even have their own streaming platform. So you can see, if you can convince the whales here, then you are going to be a huge company that gets wealthy. This is why casinos and gambling is so big here.
