WARNING TO ALL re: OFFSHORE BOOKS I don't believe the offhshore world is stable. You should be very careful choosing where you put money in this environment. Anthony is carefully checking the safest and best books to look to invest money. If the book isn't on his "best bet" list, be sure to go to sportsbookreview.com and look into how well rated a book is.
A good rule of thumb: B to A books may well be good, but even A rated books have failed. BE CAREFUL, and don't even think of putting a big investment in any one book!
Any book rated C .......your money is at risk......you have a junk bond type investment.......proceed with great caution
Any book rated D to F........Some gamblers roll the dice due to promotions/etc. No reason for you to do so. AVOID AT ALL COSTS.
Even "best bet" books have some risk. Keep balances low, and don't ever fund a book with money you cannot afford to lose. Having said that, CRIS and OLympic are likely as safe as they come, as is Pinnacle for NON US. And I don't see how MB could get in trouble, as it is an exchange.
