It depends upon are we looking for short term profit or long term. In short term with little to no effort and less investment what hyip site can earn (SCAM) can be considered higher to what bitcoin casino can earn in very short period with high initial investment and effort. However if we look at profit that some of the trusted bitcoin casino have earned within a year or two time period than we can say running casino is profitable if you can handle/solve all problems which may arise during running it.

Also running casino can be legit way to make money rather than scamming others with running HYIP site.
