Unless you are a new player and then you are throwing your money down a hole as it is close to impossible to getting enough fortune cards to stand a chance of winning. The cost of chests has gone up a minimum of 2.5x and the amount of SPS you have to stake to get them as rewards is far beyond what new players would ever do.
That might be true...
