I have visited their site and I saw another good and promising promotion they have launched, they are giving away 1 million dollar worth of price in terms of trading in their platform.
Oh really? Then that's great for all traders of crypto. Now they have the reason on why they need to be here and join in the project. They can be fully satisfied on this platform because it seems that the team of PrimeXBT are very dedicated to give them good rewards.
This may be more like an air drop which most project do to make more people to participate.
