HOW IT STARTED

First came curiosity. Then came an industry.

In 2016, Michał Stryjewski and a group of friends became interested in Bitcoin, Ethereum, SiaCoin and Litecoin. The attraction was not only financial—the decentralised idea itself challenged the traditional way of storing value and making transactions.

A year later Unlimited began operating. It grew from hands-on mining experience, hardware testing and conversations with people who wanted to enter the market but needed reliable equipment and real technical support.
