"GPT" sites or "Get Paid To" sites have been around for quite some time. Unfortunately many of them suffer from lots of the same issues. Low payout, banning right before payout, hoops to jump through and other various problems. That being said there are a few good ones that are definitely worth checking out to gain some extra income.
CashCrate is by far my favorite GPT site. They have a large variety of offers and all of their rewards are straight forward. They pay out by check once a month. Sure its a little inconvenient not to get instant payout but I have never had an issue with receiving my earnings. They have a wide variety of offers and are one of the highest paying GPT sites around. All countries are welcome to join which is an added bonus if you are outside the US.
Swagbucks is my second favorite GPT site. It offers a variety of offers, videos to watch and surveys to take. It also lets you download its search bar and rewards you with points every so often just for using it. Overall Swagbucks can be a great passive source of extra income just for using their search bar, or you can stay active in it and earn on the same level as a site like CashCrate.
This is another great GPT site. It pays you for all the normal things you would see on a GPT site. Plus you can earn points searching using their search engine. It pays out in gift cards, which isn't ideal. However you earn pretty quickly using this site. This site also welcomes all users no matter the country. In fact I believe this to be the best GPT site for non-US citizens.
GiftHulk is the final GPT site I recommend trying. It has the largest amount of tasks to complete but it also doesn't pay quite as well. There are a variety of free and easy way to make points each day just by signing in. After that you can decide how much time you want to spend on it and how much you want to earn. Again this site pays out with gift cards which while nice, aren't cash. Though this is a small price to pay for a great site.
