ShapeShift was founded by Eric Voorhees in 2014. Online exchanger based in the Swiss town of Geneva. The main function is the quick conversion of bitcoin and popular altcoins with the highest possible protection of transactions. The peculiarity of the exchange is that client assets are not stored on the site itself. And this, undoubtedly, increases the security of the service, although it somewhat impoverishes the functionality. You can find more information on the ShapeShift team and the project here.
