CheckSig and its team

Bitcoin, the digital equivalent of gold, is one of the best performing assets of the last decade. As a new asset, it requires specialized skills to be properly managed.

Furthermore, the crypto world is still a “Wild West”: do-it-yourself solutions are risky. Crime, scams, technological missteps, tax and regulatory issues: it is better to count on a reliable companion for your crypto journey.

Meet CheckSig and its team.


The company

CheckSig origins

It all began with the Digital Gold Institute (DGI), our consulting, training, research and development center on Bitcoin, crypto assets, and blockchain technology.
At DGI, professionals with varied expertise – finance, academia, banking, strategic consulting – came together and found investors needed a reliable Bitcoin and crypto partner.
