Goldman Sachs - Adviser in Easter Europe. I am a serial advisor to projects with a great potential, new solutions, connecting them with all necessary support such as consultants, marketing and community managers, crypto funds and investors, crypto exchanges etc. Following bitcoin’s launch in January 2009, the price remained below $1,150 until February 22, 2017, when it jumped for about 10 months. This growth ended on Dec. 17, 2017, when bitcoin reached its peak price of $19,511. Such dynamics were not caused by overall market fluctuations, as indicated by comparison with the Standard & Poor’s 500 stock index, the researchers noted.
