Today I've joined three new PTC websites. They work some time so I think it should be stable. Two of them (
ChillBux and
DingoBux) I test only, without investing any money. The third one is
Earn3 - old PTC with many members. I think I trust them so I've
rented 100 referrals for one month ($36.36). If I count good the investment should refund in 7-8 days (~$5/day). This should give me over
$110 revenue! Sounds good. Waiting for my first payment :)
