Our take

Blockchain.com was founded in 2011 with the aim of making Bitcoin more compelling and efficient for consumers. It's now the world's leading provider of digital currency and distributed ledger software, with over 35 million users and $1 trillion in crypto transactions conducted on the platform.

Cryptocurrencies have become a fundamental part of both financial and cultural life. And yet, their world is often still murky and confusing to the uninitiated. Blockchain.com have been focused on bringing further exposure of digital assets to mainstream audiences. As part of this, the company partnered with the NFL team, Dallas Cowboys, which has bought with it branding, advertising, content and event opportunities.

The company has impressive funding at its back, that was raised in an otherwise turbulent time for venture capital markets. This stands to signify the attractiveness of the company to investors, which certainly bodes well for its future success.
