i received my first payment from Upbux one week ago, instantly via Paypal so no, it's not a scam, Upbux is as legit as Neobux! And i hope they won't turn into a scam in the future! I only trust Neobux and Upbux now.
I use this site and it's paid me..it's not a SCAM, lot's of people use upbux, neobux etc. It's not a scam, also upbux have very good security, games etc. Paid Instantly, so..it's one of the best buxes. Regards.
