Mission and Vision


Gastcoin’s mission is to help spread the use of cryptocurrencies in a socially useful and relevant way. Cryptocurrencies are the tip of the iceberg of the blackchain world and, although in recent years their purpose seems to have shifted towards investment and speculation, we must not forget that they are tools with the potential to change the world if the right vehicles are developed. Gastcoin Gateway is one of those vehicles, as we want to bring the use of stablecoins around the world into everyday life.

Gastcoin S.L. has as its target market every person in the world who wants to make a transaction, whether commercial or personal. Gastcoin allows to make “person to person” commerce a reality, avoiding intermediaries to dictate the rules.

We want to constantly reaffirm our position among merchants and their customers to be the leading brand so that they do not hesitate to choose us for their cryptocurrency transactions.

We work to constantly raise the level of the world’s crypto experience to help people buy or sell anything and improve their day-to-day lives.


We strive every day because::

  • We work for and for our clients, so that they only have to think about what is really important, growing their business, and for our investors, to maximise the return on their investment..
  • We work for decentralisation and transparency, because the simpler a system is, the further it can go.
  • We encourage entrepreneurship and responsibility.
  • Our favourite way of thinking is… LONG TERM!
