I don't know the credibility of their claims, but i have come across quite a number of games online, where you are asked to play to earn btc, lol.
Have you come across any games like that?
If so, did you really earn any btc?
There are certain casino outside there which let's user earn Bitcoin or some other altcoins just by playing games available on their platform.But the rewards are very low even if you play for long hours and there are certain regulations like KYC to withdraw your funds, limitations to specific amount that can be withdrawn.But the most important is why they are paying you btc or some other coins just for playing games?
The reason is if they are legit casinos or any service provider paying you in btc they are earning from you.Thats right.
1) Revenue from ads: Whenever you play games there are certain ads popping on your screen in between and whenever you click on them the casinos get paid from them and you cannot play games with adblocker on your browser.Each time you click on the add they are earning and paying you fraction out of it.
2) When they want to promote themselves they distribute free coins which in turn came back in the form of deposit by the new members which join the casino
So you can say that there is nothing free in this world.You pay for it to get it.
