Wow...so much unchecked bad info in here. 1.5% / mo is 18% per year - it's well within the range of attainable returns for straight investing in a variety of moderate risk vehicles. You get paid to take risk, not sit around and play it safe. If you listen to these broke ass clowns telling you anything that pays that much is a "scam" you'll end up just like them - and I know for a fact several of them are scammers.
Scammers cant really be avoided and as a wise investor we should not really fall out easily on those too good to be true investments sites that do offer too good to be true returns and speaking with 1.5% monthly is attainable actually there are legit websites you could actually search in fact even on bitcoin itself you can also achieve this.
The only site i know where we can earn that percentage monthly is in trading site and casino investment site! and in that to type of investment choices is i think the most safest since we can actually see how it will works and we are the one who's gonna play our faith in tradings and same in casino investment we can guarantee to earn but we should select to invest at the big sites since surely they are the one who's legit and can give us real income.
