when it comes to gaming, i’ve been buying the stocks of the 3 easiest to play/biggest macau casino players, las vegas sands(venetian, LVS), Wynn and Melco (crown casino, MPEL). In 2006 macau beat vegas in the amount of gaming revenues and i think it will keep growing rapidly as the new hotels open. That’s where i’m investing in gaming.
For poker players, i would spend the money on paying a CPA for depositing/active players. I would recruit people offline, who aren’t internet affiliates to distribute coupons or disks. The better control you have over stats, the better you can get at getting rid of scammers.
