Happy to report that all of my XRB has been moved off of Mercatox successfully! The nightmare is over

Seems legit. 

With the popularity of ICO's growing, you need be on a constant lookout for scams. People will trip over each other to offer you their affiliate links.

Do your own research and look at everything from the team, developers, site, whitepaper and ask yourself if this coin actually serves a purpose.

When you join an ICO, email support and see if they even respond.
