The enormous growth from $974 to $20,000 per coin means that 2017 is definitely the year of bitcoin’s glory.
The growth of the last month is probably a result of a big push from Wall Street futures trading and the expected adoption of the Lightning Network. And all the big noise about bitcoin in mass media was one of the main reasons of its growth during the whole year. The Coinbase app already has been at the top of Apple’s “most downloaded apps” multiple times.
Today the experts are focusing on how governments will react to the outstanding growth of bitcoin in the forthcoming year. In official circles and mass media, there is still a tendency to call Bitcoin a bubble, even when the big players have shown up in the game.
