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.
Yes people are expecting more from the bitcoin every year,we should give some time it to recover from the crashes,fist we need to forget about that all time high of bitcoin price we just compare the price of last year and this year still the bitcoin made phenominal growth.But as OP said we may see some fire works at the end of this year and $12K is decent price and more will be contented with that price so we need to buy it now to enjoy when the price reaches $12K
