It is certainly possible to earn $100 a day, but earning that much daily on a regular basis from taking paid surveys alone remains difficult for many people. It is because survey eligibility will depend on your country, profile, age, occupation, and more, so there will be many variations in earning. The individuals who manage to earn more money generally do it through using multiple survey websites and participating in focus groups, research interviews, product testing, app testing, and referral programs. Thus, the money is indeed possible, but it does not come easily.
