When I think of “International” in regards to GPT sites, the first two sites that come to mind are:
CashCrate pays via Check, and also has prizes such as Amazon gift cards, and more.
PrizeRebel pays via Amazon gift card, PayPal, and more.
Not every site allows for international signups, and there may be less offers than there are for US signups, but there are definitely ways to make money on international sites. Once you’ve completed all of the offers available to you, referring other members is a great way to earn money. Both of these sites have a great referral system as well as great payout options. They’ve both been around for a long time and have good/known reputations online. Go ahead and check them out! Click the links/banners above to see for yourself.
