Why will Freebitco.in go "RIP" over a simple adjustment in the probability that you will win a specific prize? Casinos make adjustments like this all the time. Let's take Stake.com as an example... they had VIP hosts for all Platinum I players and higher ...but the amount of people that reached Platinum I increased so fast.. that they decided to stop offering VIP hosts to Platinum I players... and only for Platinum II players and higher. (I think they changed it again ...now it is Platinum III and higher)

Casinos have to constantly balance the expenses to be less than their income... other wise they have to close their doors. (They are doing this to make a profit... not to function as a charity)
