Recently, I developed many finance sites and I get interested in BlockChain. I have experience of constructing my own Blockchain system as well as using prior Frameworks. Currently, I am implementing the crypto currency exchange with using APIs of Shapeshift, ASP.NET, C# and etc. Exactly I am developing the Alohacoin exchange for trading from Alohacoin to BTC and vice-versa now and it's almost developed. I'd love to develop better service.
