No, I think you should remove one zero. Looking at the market now, $10k or $15k at the end of 2018 would be good. 2019 may be a different story, however.
You think we should remove. Maybe for end of this year we might see this 15k to be maxed price but believe that next one will bring some new ATH for many coins not just bitcoin. Last price was in 2013 four year passed and we saw in 2017 now believe we will see in 2019 something similar if not the same. This year will be stability more rather then price increase.
Yes, there may be a new ATH in 2019, I would not be surprised by it in the slightest. This year will be either boring (going sideways for months, and this is a good scenario) or bearish.
You cannot predict the future but I think it will not really happen. it is too heavy and I think the bitcoin movement will slowly. and if yesterday bitcoin crashes up to $ 6K, too far if this year will reach $ 100k but if to go to $ 30k it is very possible and the odds rise will be stable. The main cause of bitcoin increase and depletion is due to news. and those who have substantial capital are very influential in influencing bitcoin prices with their issues which they spread.
