Blockchain.io has a real vision, a strong leader (well established in the crypto-world) surrounded by a team of real professionals, and the financial strength to support such a project.
Blockchain.io offers new forms of financial liquidity to companies that want to raise money for their startup project. At the end of the day, we are talking about real value creation (as new startup companies create products, services and jobs).
This is the most important aspect that makes me believe that this company is completely viable, compared to other companies that may offer similar but speculative value propositions.
