"We are now entering the third stage, in which core financial infrastructure and services will be built by veteran entrepreneurs backed by institutional money, and in accordance with the regulatory framework of the United States and other nations. This stage will end with mainstream adoption of Bitcoin and consolidation of Bitcoin companies as large financial incumbents embrace digital currency."
"The fourth stage will begin when Bitcoin becomes a widespread medium of exchange and can be used to revolutionize industries outside of financial services, such as real estate, contracts, supply chain, and machine-to-machine commerce."
"The promise of Bitcoin is self-evident. The financial services industry has not seen much innovation over the last 50 years, and digital currency is poised to deliver 50 years worth of innovation in the next 18 months."
Whilst I respect and believe in the multi signature technology you are promoting, I fail to see how it could have protected MT.Gox users from what was basically non-existant accounting audit practices. The theft from MT.Gox may have been going on for as long as two years!! and in all that time they failed to notice that the sum of their customer accounts did not come close to the sum of bitcoins in their hot and cold wallets!! That is incompetance of the highest magnitude, which was only multiplied by the incompetance of their software team failing to design/implement the Bitcoin protocol properly on their wallets.
