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.
