i guess due to the worsening housing market, sky rocketing fuel prices, overall rising prices for food and clothes, people simply have not that much money left to play. If they do play and lose most of the time they switch to another casino hoping for better results. Besides that depositing options for US players are not that many anymore. It takes time for new players to get to used to these.
For RA i had a player who deposited $200 wagered 100K (with free play money and an additional bonus) and won $1000 and cashed out. Because i am on wagershare i earned $750, not bad! I see some players play for the first time, after signing up months ago.
Some months with RA are better than others but the guaranteed earnings is what i like the most.
Competition is fierce in this industry new sites every day so clicks are not telling the whole story : Most of the time players get attracted if there is a new bonus promo, click on it and download stuff. But these players may already be registered with the casino thinking to get a better deal afterwards.
