The problem is that these brick & mortar casinos are only paying it forward, because they are required to do so by law.
I know that there are a lot of charity-giving people in the crypto community, but I doubt that casino owners are among them.
I would think that they think about profit in the first place, so they would most likely not give back to the 'community' unless there was something in it for them.
There is something in it for them. When you are the main sponsor of a Bitcoin event, you get prime advertisement for your
business and you build Brand recognition. You also increase adoption by sponsoring large tournaments. The biggest Casinos
are offering Sports betting & eSport betting services, so they can even host a online gaming tournament with the help of the
community and gain new gamblers that would be betting on the outcome of these tournaments. The Bitcoin gambling and
online gambling scene is very competitive, so things like this will set it apart from the other 100's of casinos out there. I can
already envision a Bustabit or PrimeDice sponsored global online gaming tournament.
{Arranged by the community and
funded by the casinos}
The games can be streamed live with advertisements all over the place and people betting on
the games.
Looks like I didn't think that reply through enough
You're right that they would get free advertisement in return, but is it really 'paying it forward'?
I was more thinking about casino's offering to help with paying for development of Bitcoin or other open-source projects.
I personally just don't really count hosting a tournament as 'paying it forward'. That's just my opinion though.
