They promote a website for money in which many gamblers are losing their money. In fact it is a crime and action should be taken against such videos so that they don't promote a scam to earn money. 1xbit knows they will get lots of promoters if they spend money, we should break their confidence. 1xbit scamming reports are coming out every day which is not good news for the gambling community.
I want to say that those who promotes a scam site or a scammer those are the part of the scam or scammers. Though they are spending money and getting traffic but they wont be able to make profit as no user will repeatedly visit as once they suffered they will stay away and will try to keep away others.
They promote the scam website to gamblers who are inexperienced with such scams. Websites like 1xbit target gamblers to make a one-time deposit. And once the gamblers deposit money on this website, then the scam website team freezes the funds with any excuse. So these websites generate revenue by scamming their customers and use those funds for marketing.
