Trying to get a grasp of history and making some predictions. Improvements are welcome! I always thought that price might stabilize over time but I'm not so sure any more.. Though I don't see any reasons yet for Bitcoin to stagnate.

2010: Experimenting
2011: Started to grow
2012: Acknowledged by the world, promotion
2013: Acceptance by small companies, turbulence, politics, super hype, venture investment boom

2015: Price recovery, merchant acceptance boom, acceptance by some governments
2016: World wide acceptance, network expanding and huge rise in mining power, ATM boom, scaling war & Bitcoin politics
2017: Cryptocurrencies boom full spectrum, Japan accepting Bitcoin as legal way of money, other important acceptance, (scaling compromise and solution, potential forking turbulence)
2018: Serious cryptocurrencies development and altcoins finding their purpose, large network scaling, big fresh investors, price boom v.2.0
2019: Serious push for mainstream adoption in some countries, mixture of cryptocurrencies and interoperability
