Bitcoin is the most famous cryptocurrency. Undoubtedly it is a breakthrough in a financial world, and it causes a lot of discussions. Some specialists think that it is the future of finance and others believe that it will not last long. Bill Gates, one of the business giants, thinks that Bitcoin is exciting because it shows how cheap it can be to make transactions and gives full anonymity. However, Warren Buffet believes that it will not be around in ten years. He thinks so because Bitcoin does not meet the definition of currency at all. But Julian Assange believes that Bitcoin architecture has applications far beyond the economic role. That architecture is very strengthening to the life of information in the digital space, making it less vulnerable to any kind of mischief. Richard Branson shares Assange’s opinion believing that in future there will be Bitcoin-like currencies that may be even better.
