any by the people metioned , heres trevons video but also check craig grant he has made many videos explaining it also he promotes other peoples videos thru his channel. , heres a vid where a guy is profiting with no referrals. i myself at 9 nine days am at $5.27 and i have no referals and only $120 put into the service . its not a scam its just people read too much into it with the volatility there are low days but honestly it makes up for it with the days where the percentage is higher . the sites been up since like 2016 its only picking up traction due to interest of youtube personalities . i understand where you would be skeptical but you should look into it dont look at the negative videos those just will scare you away with no proof cuz the people in them dont try it themselves .
