About

BlockTech (originally known as CRATR) was founded by professionals from the software development industry and derivatives trading industry.

By combining knowledge and experience from different fields, we were quickly capable of securing stable revenues from trading algorithms in the cryptocurrency market.

Currently we are active in the field of cryptocurrency options trading, a new and fast growing derivatives market that is rapidly expanding. Our aim is to expand our current backbone, which consists of both Bitcoin and Ethereum options and futures, into more types of cryptocurrencies and exchanges.

As a company, we believe we can help shape the future by developing tools that help improve trading practices and liquidity within the market.

Mission

It’s our mission to improve transparency and increase liquidity within the market

This is what has made the company successful so far. We believe in a democratic trading system in which participants should be free of counterparty risk. But our goal is to go further than this.

Blockchain technology is relatively new and we believe it will change the future. We want to be on the forefront of these developments, create new ways of using blockchain technology and help develop innovative software in the process.
