Bitcoin in 2018 is strongly adjusted. Many investors have lost hope in this market. However, I think this is a necessary and reasonable adjustment, I believe that the end of 2018 will have a strong rhythm for bitcoin.
Many investors lost their faith in bitcoin because they expected too much from it, and also I share you opinion that 2018 will be a year of adjustment.
And yet again some people expect that bitcoin will reach new heights at the end of this year... which is not impossible, but I doubt that. I think, all that we can expect from bitcoin is to reach stability and to start rising slowly. Maybe in 2019 we would see new heights, but as for 2018 I think we should be happy if we see price of $12k.
