How do you make money on an online casino?
Sure you can, but there’s a better chance that you will lose money.
I’m going to assume that what you want to get at with your question is whether they are legit or not?
Like any other business enterprises in this world you will find all types of online casinos, legit and not. What you want to look out for before depositing any money is the license seal at the very bottom of the casino website. This shows you under which regulatory body the casino is licensed.
I suggest you play on casinos registered in Malta or the UK since these are highly regularised. Unfortunately these casinos will not accept US players.
Alternatively you can ask on one of the many casino forums available on the web, like askgamblers.
Simply find some trusted resource, and that`s it. If you want a sport betting app, or website I can recommend using bovada betting which is a good way to make money while you are traveling or watching your favorite sport. There are a lot of different information about sport matches etc. Best of luck
