yeah, it's not the most ethical investment in the world but these sectors like gambling, drugs, alchohol, cigarettes, sex, guns, ... tend to do well both in the good and the bad times. Basically that is what it is, people who can't help themselves gamble all their money away and it goes to the house and the ones invested in the platforms.

As a player it's actually possible to get something out of it if you have your emotion under control and do the needed work. At least for me this last decade that has been the case even though it remains a real challenge. Being on the other side as an investor is far easier :)
