I haven't watched the video because I am obviously sure that no such strategy exists which guarantees a profit, but I visited the link given in the description and it took me to some wild casino (literally, that was the name of the site after many redirects) and it was a referral link from what I understood. If someone is sharing referral links, it's pretty obvious the guy is trying to earn by affiliate revenue and doesn't have a working strategy. If you have a working strategy why would you need referrals then.

Also if ever there was some trick that somehow existed to make money from casinos, it would be exploited rather than being shared.
