Dear @kingscrown, passive income is one of the most important facotors of my education and I highly value what I'm reading here about MN. However I don't understand this one section

EXCL, cost 3,5k, ROI - 42%
SMART 837USD coist, 67% ROI
XZC 28k, ROI 25%

Is there a way could elaborate on these 3 as they seem pretty accessible for me, unlike DASH and PIVX. Even if you drop a Dtube clip or forward a YouTube clip that makes reference to the 3 you mentioned?
