It's indeed a hard task to complete, and to say the truth, many influencers are successful on this niche by deceiving and lying to their audience, what I think doesn't really worth after all, because the money coming from this will be a cursed one.
Yes only gambling influencers will be successful in getting a lot of money and bonuses from referrals because they always manage to cheat their audience and earn a lot of money, it will not be useful for regular gamblers because it is difficult to get bonuses and money from these referrals and obviously it will just be a waste of money just time and it doesn't produce anything because I've tried it and it doesn't really work.
Influencers who work in the field of gambling definitely have an audience of gamblers too, so it is very easy to earn a lot of money and the referral bonuses that can be obtained from casino sites, whether they are valuable or not, all depend on how the influencer uses and claims the bonuses well so that they make a lot of money.
