PTC Box was launched in December 2011. It is owned and run by the people behind MatrixMails, a successful PTC/PTR site that has been online and paying since 2002.
Ads: PTC Box offers about 7 ads per day that pays $0.005 per click for standard members, and up to $0.055 for upgraded members.
Payouts: Payout limit is $2 for standard members. There is no payout limit for upgraded members. Payments are instant and sent via PayPal or AlertPay.
Upgrades: There are three paid membership types: silver ($30/year), gold ($60/year) and platinum ($100/year). In addition to a higher per click rate, upgraded members get advertising tokens, higher referral earnings, more referral levels, 30 cent referral bonuses and bonus referrals. One unique feature of PTC Box is that you can customize your own membership type, and pay only for the options you want (extra levels on referral, earnings multiplier, referral earnings multiplier and signup bonus multiplier).

Referrals: Standard members earn 10%. Upgraded members earn more, depending on membership type. There is no limit on the amount of referrals you can have.
