It is enough to see the historical performance of bitcoin to discover that the year 2017 was so extraordinarily exceptional with respect to previous years, that perhaps it should be left aside when using statistics and mathematics to make an attempt to forecast the possible scenarios of the bitcoin in the medium and long term.
Therefore, based on what can be observed in the years prior to 2017, I believe that there is still enough space for the correction to continue and it is possible that throughout this year we continue paying the consequences of the excessive ambition that took over the market last year, and we finish this 2018 in the red.
2017 was superb. We could see more red in 2018, but there is a possibility that because of a big jump in 2017 lot of people heard of crypto and they will maybe step into the game with fresh investments. That could be a step towards green, but this is not the only thing that could affect the movement in any direction
