Our take

Cryptocurrency provides a near-instant and anonymous way to pay and receive money. This is a boon to legitimate business, but it's also a new front for criminal activity - in 2022 alone, Crystal Blockchain Analytics reported that over $2 billion was lost to crypto theft. This is why the company supplies a blockchain analytics tool for regulators and criminal investigators, to bring oversight and stability into the cryptocurrency market.

Crystal's strength in this sector is the breadth of its data, covering the vast majority of both centralised digital assets and decentralised finance products. As a result, its predictions and market visualisation tools are considered best in class, and have been used to solve major criminal cases involving ransomware payments and money laundering.

The company was developed by Bitfury Group, and benefits from the group's blockchain expertise and marketing reach. It continues to add talent to its senior team while actively expanding its client base and acquiring several companies to support its growth. it's also increased the number of blockchains that can be monitored through its platform - adding the likes of Polkadot, Arbitrum and Avalance - which now means the company can provide transparency to over 30% of the world's chains.
