I have couple questions about this service:
1. How much will I got paid for 1 survey (there are one rate for all surveys or it may vary)?
2. Is there a limit how many surveys I can take daily?
3. Is some countries excluded by the system and I need to be first world citizen to have access to most surveys?
1. It varies from 50 bits to 10,000+ bits, all surveys pay differently!
2. No limit to the surveys
3. I don't know about exclusions but some countries get more offers than others. Everybody can still earn from referrals though
