Because people are practically nowadays and they know how HYIP's are working and there is only one description that has everyone will agree with it, it's a scam.
Yup, most hyip's are scam and thats why hyip's will lose their users from time to time and of course they will have less profit than bitcoin casino sites. House edge gives a lot of profit for bitcoin gambling sites and the fact that most gamblers will lose their money is the other advantages for bitcoin gambling sites.
