Coinviable Investments is a big scam. They have agents out there placing good reviews on the internet. I am giving you first hand information. There is one person in support 24/7 named Marian, he will trick you to send bitcoin in return for a bonus. Ask him to diduct the payment from the bonus and send you the balance, but he will refuse. Their agents will tell you how its a ligit combany because they were winners in the past and got paid.<br />
Just look at their investment plans, can they pay those returns they promised? Just be careful, the are scammers in high places once they get your money they will not refund it.<br />
Check out their address in the UK that is also a scam. That address is listed for hundreds of companies.
