Interesting comparison, question that is unanswered is what is the Skype in Bitcoins...is it Blockchain or is it Cryptocurrencies....people tend to increasingly it is the block chain, which makes a comparison to Mosaic more relevant than to Skype....
Michael Jackson, former COO of Skype and current venture capital investor at Mangrove Capital Partners, explores how bitcoin companies can learn from the early struggles Skype had with regulators across the globe. For all the differences between Skype and bitcoin, there are many similarities. Both products use fundamental changes in technology to enable new opportunities, and they both remove the existing organizational hierarchy of their respective industry. As such, parallels can be made and valuable lessons can be learned from the early days of Skype.
