Is mastercoin.pro Safe?

Learn more about scam sites I did a lot of research and registering on various sites and found that most of these sites are scams. An example of these sites: mastercoin.pro I have invested in this site. I have withdrawal my account several times on this site, But after the last withdrawal they blocked my account. I have visited the site several times but have not received an answer This site does not have good support and this is suspicious After several successful payments, it will freeze your account Please warn your friends about investing in this site.

It's scam, i have invested here but they are tricking peoples. At the first they will payout but after sometimes then they stop it without reason, when we start questioning they block chat messenger and then they suspend our account without any notice. I've invested $200 and never get ROI.

***** is a SCAM company, they will pay for only few investor and steal from large investor, i have received report from my groups that many of them didn't get the payments, this is including my own experience who invested altcoin ($100), at the first i could earn/withdraw normally and then they suddenly stop my payments at 5th withdrawal until now. When I made complaint to cs support they simply just block my chat feature.
