If you can do what you claim -- use astrology in such a way that you never have a losing blackjack session -- that will easily qualify for the million-dollar prize offered by the James Randi Educational Foundation:
One Million Dollar Paranormal Challenge
The Foundation is committed to providing reliable information about paranormal claims. It both supports and conducts original research into such claims.At JREF, we offer a one-million-dollar prize to anyone who can show, under proper observing conditions, evidence of any paranormal, supernatural, or occult power or event. The JREF does not involve itself in the testing procedure, other than helping to design the protocol and approving the conditions under which a test will take place. All tests are designed with the participation and approval of the applicant. In most cases, the applicant will be asked to perform a relatively simple preliminary test of the claim, which if successful, will be followed by the formal test. Preliminary tests are usually conducted by associates of the JREF at the site where the applicant lives. Upon success in the preliminary testing process, the "applicant" becomes a "claimant."
Read the Challenge FAQ for more details. As you will see, to get started all you have to do is explicitly state what you claim to be able to do, under what conditions, and propose a fair testing procedure. If you and JREF can agree on the conditions and the testing procedure (which really shouldn't be hard to do in this case), you're on your way. (I'd suggest that you propose doing the test at a real casino, so you can win the million dollars while doing what you're presumably already doing: raking in all that casino money. Plus, just think about all those skeptics having to eat crow -- that alone should be worth the effort -- but don't forget about what the movie and book rights would be worth!)
If you decide you're going to apply for the challenge, you might post your proposed application on the JREF forum first, and people there will give you objective feedback and help you design the test. (That will probably save you at least a couple of rounds of e-mail with JREF.)
On the other hand, if you decide you're not up to the challenge, I do hope you will show the people here the courtesy of not clogging up this board with a mountain of excuses and rationalizations. (Astrologers and "mediums" seem to be particularly prone to doing that.) Whereas there are billions of people on the planet who would be interested in your successful winning this prize, it's hard to imagine anything more boring than the excuses for why you won't even apply.
(I am now placing my psychic prediction about whether you ever take the challenge in a sealed envelop. Unfortunately, such predictions are not eligible for the prize, since there's nothing paranormal about them.)
