On your website it's written that:

"Your compensation amounts and wallet balance are always available for you to see".

Though in whitepaper it's:

"Now John has joined the Biotron nation of millions of people who make money and improve our world by voluntarily sharing their data".

Maybe I've been reading not attentive enough but I haven't found an estimate of the user's reward. Or the word "voluntarily" means that user's main goal is to "change the world", not earn money?
