Am I the only one around who feels like an ATH by the end of this year?
You are not the only one, but you are likely within a considerable grand minority.. amongst an elite few peeps with such thinking ---- not including yours truly.
For me to consider ATH to be plausible for the end of the year, the odds would at least need to be above 50%, and I doubt that the odds are even close to 50% - you would be lucky if currently such odds for an ATH before the end of the year would be greater than 30%...
So accordingly, it does not seem reasonable to me to be projecting for something with such low odds to be occurring, and the way you expressed the matter, you seem to be under a kind of belief that such odds for an ATH by the end of this year were 80% or greater, which, at this time, seems pure crazy-thinking to me. ... approaching a kind of lunacy...

... hey.. I would have said the same thing if you would have asserted that we would see anything above $14k in 2017 - before August 2017. for example, things were seeming quite dire for then BTC price dynamics.
On the other hand, I would agree that if BTC's prices continue to go up from where we are at now (in the sub $9ks) and to stay up past certain price points, such as being able to stay above $10k for a decent amount of time, then Lindy effect principles would suggest that projecting even higher BTC prices becomes more and more within the ballpark of reasonable (in other words the odds for ATH in this calendar year becomes higher and higher... so... little by little to increase odds and to cause more and more FOMO wins the day, as Jimbo likes to say).
