Vinexcoins.us is a fraud company. They are asking to invest. They will tell they are investing you money in Cryptocurrency and they will pay return daily 15% to 50% interest depending on your investments. But after investment when you are giving request for withdrawal they are asking more money in the name of insurance fee or any other investment or referrals. They have Telegram group and Chatting each other's like they are investor and they are getting return everyday, but that all are fake Chatting. They won't give your money back. So be care full.
