Plus coinurl is too much problem, be presumed as scam site (you can googling it).
Only one out the 69 lists it as malicious, the rest say it's clean so it's probably a false positive. However, as with most link-cloaking sites they make their money from pop-ups with some no doubt being dodgy so maybe that's why. I haven't used either to earn but have used them to download files so cannot verify how legit they are in that respect.
