Toluna is a good site and a completely legit site. You can trust this website. They pay as they promised. I am a member of toluna since 2017 and still earning money, gift cards from here.
It is true that you can not earn a big amount of money but you can earn limited extra money from this site. Here you have to answer the survey, create polls and ask for an opinion. Every survey offers 1200-5000 points. They have criteria of 50000 points for 500 INR. They offered many types of reward like gift cards of Amazon, flipkart, Nyka, Big Bazaar and give money through Paypal.
To receive the reward through Paypal you have to wait for some weeks patiently but the gift card is processed faster than Money reward.
Overall its a good website for all those people who wants to earn some extra bucks in their leisure time.
