## About 100x Group

VC Fund

100x is the result of the phenomenal success of BitMEX, the world’s leading cryptocurrency derivatives trading platform, which has pioneered cryptocurrency trading through relentless commitment to change, and continues to set benchmarks for innovation, liquidity, and security today. Financial services play a critical role in their economy and dailylives, but have become cumbersome and expensive, and remain slow to transform in the digital era. They formed 100x to ignite a bolder ambition—reshape the modern digital financial system into one which is inclusive and empowering.
