I have $3000 USD to invest, is it worth it?
What sort of returns should I expect
Same like any kind of investing you can expect alot of profit and also must prepare to lose all yours money... And both that possibility could occur on shor or long term, mostly base on yours investing contract/rules
In investing in an online casino losing and winning is just normal, if the casino wins then you make profit because you are part of them. Just remember that when you put your money don't think that you are very safe even though casinos win all the time but still there are other factors that will make you lose.
most of the casinos are not directly involve in gambling, they just collect the fee or their fixed percentage. therefore investment in casino is ok and there is no risk in it, but you must be careful to invest your assets in a legal casino and not in illegal casino.
