Toluna Influencers is an easy-to-use paid survey site with quite a lot of available surveys and you can also download their app to take surveys on the go.
Even though Toluna is a great paid survey site, the reason it is not higher on this list is that it only offers Bitcoin as a reward in very few countries even though it is available in 60+ countries.
Bitcoin payout threshold: $10
Other payout methods: PayPal, gift cards
But if Bitcoin is not available in your country, you can get paid via PayPal or gift cards.
