PocketMoneyGPT is a PTC site, that includes surveys, completing offers, watching adds, contests and a referral programme. Plus there's a 0.25 bonus for every 5 offers completed.
Most offers pay in coins instead of money, but you can convert the coins to money either way. (The button to convert appears only after you gain coins)
It's a fairly old site (4 years old) that has undergone some updates lately.
It pays in Paypal and Amazon gift cards instantly. Payout minimum is at $1.
Their referral system allows 3 levels (a small train), and you gain $0.30 for each referral.
Note: Upon registration they ask for a real name, a valid phone (verified later) and an address, to avoid fake accounts.
