The Idea

Immediate conversion of assets

Its main objective is to be a gateway to the flow of assets between investors and existing exchanges. Supporting all the popular online payment methods, it allows the investors to convert funds from fiat currencies into cryptocurrencies and vice versa in a very short time.

Sint App

Coming in 2018

The Sint Platform is a basic tool for newcomers and experienced investors operating on the cryptocurrency market. It will enable conversion and transfers of funds held in any currency into cryptocurrencies. Most importantly, it will provide a comprehensive solution bridging the gap between funds accumulated in banks and large cryptocurrency exchanges.
