Cashium is a new PTC that just opened up their beta phase (no ads until this phase is over), where members who register during this phase receive a special membership called "discoverer" (benefits will be implemented later). Not only is this site visually appealing, the admin has set up a solid business plan, which will undoubtedly attract investors and ultimately aid in Cashium's longevity. This plan is tree-fold: 1) A tier system for referrals, where you receive credit not only for your own referrals, but also for your referrals' referrals up to four "tiers". Better yet, there is no direct referral limit! 2) A multiple referral renting system, where one member can be rented out to up to 10 people, so that there will never be a shortage of referrals to rent. 3) Cashium points, which are earned through investing money into the site and can be used for purchases.
