Various commercial and other organizations need information about customers and interested parties in order to develop their strategy. The easiest way to do this is with a questionnaire, but they don't have a mailing list. Many companies build a mailing list and send questionnaires to the people on the list. In return, you pay money to complete it. Not large amounts, you won't get rich from this, but 15-30$ per month is not bad for anyone. Let's look at some companies that deal with this, join and earn a little extra money!
The company has been on the market for a long time and pays stably to Revolut or Paypal accounts. He usually pays HUF 0,5-1 $ for a 10-minute questionnaire, and he can earn HUF 15-30 $ per month only from here. It only has a mobile application, it does not work on a computer. You have to pay attention to the notifications of the application, because you may miss the deadline!
