Depends on the personal situation. An extension with 2 million users can generate a very meaningful revenue. My extension has only 300k users, but offers that I received over years [0] would have been significant in some lower-income country.
For example, your income for the 10k users will be ~ $ 1000 per month, users 20k ~ $ 2000 per month… 100к users ~10 000 $, and so on.
ARPDAU (Average Revenue Per Daily Active User) basis - In average we have $0.007-0.011/user, US is $0.018.
Surely it's reasonable to assume that a company doing some dubious 'marketing intelligence' scraping of people's data from a Chrome plugin is going to both inflate the numbers they put in offers and try to scam their way out of paying if you actually accept. I wouldn't consider them real offers. They're marketing. The real world payments, if you get them, would be lower.
