Wow I think its rather a fair deal if indeed you could $2 in a week.Is the app accessible world-wide to work on and its also good that there are multiple payment options that can be easily accessible such as crypto currency.I think without refferal there is possibility of you earning up to $2 in a week and you can convert it to bitcoin , but i think earning also depends on the prics of etn , because when the price goes high you earn more i thinn, sk that is how it works
