Block Inc, co-founded by Jack Dorsey, has launched a Bitcoin hardware storage device called BitKey. The compact hexagonal design aims to address concerns surrounding Bitcoin security and self-custody. BitKey allows users to take control of their private keys, eliminating the risk of assets being mishandled or lost due to centralized entities.

Block aims to make Bitcoin management accessible to a wider audience with an affordable yet secure solution. Dorsey's Block is also advocating for mainstream cryptocurrency acceptance and democratizing the Bitcoin mining industry.
