I would do this because casino's are really getting popular and the gambling scene is getting more popular everyday.
Yep and even if the bitcoin casino you are investing isn't that popular at the moment, with promotion and advertisements, it will soon. So you better invest in a bitcoin casino even if it is still not that popular because it will eventually become popular unless something bad happens in the website. Also it is a good investment because a lot of bitcoin casinos have been there for a long time which means you can get paid for a long time if you invest since the start of the website.
Casinos were great up to a few months back. Now it seems they re all over liquid. Lots of people have invested and profits per BTC are really low.
