Platinum III more is worth.

Cause, there is no reason for use especially not high roller to keep active:
1. We don't get offer, like @AHOY say. If you active you get less offer than being inactive
2. It's to much waggering for rank up.

Rather than spending on the things we are usually not get, better spending other casino who offer you with good promotion like multiplier contest and other. That's why is worth to tried, spending the money on other casino who give you promotion + chance to rank up easily.
