Almost ridiculous
After having seen good reviews about this kind of websites, I joined some of them to try it - thinking of payout amounts just like those from learning rewards (Coinbase, Coinmarketcap, ...)
Rewards can be earned with a.o. answering surveys etc.
Some of them let you withdraw with minimal $3 or lower treshold.
this took me even up to 8 hours ! in my country that will buy you 1 bread (800g) only. Lucrative this can only be in very poor places.
A lot of the offers seem not to be targeting your consumer profile and don't give you DQ-points after rejected/failed introduction (that takes several questions and time)
One site showed earned points that could be calculated into $, but seemed to have cut of 33% at redemption destination.
A few surveys didn't even pay (after completion) at all, with approved status !
