The real question will be asked if we near the $2000 wall $1827 is unlikely to be the peak in my opinion.
The question today is if it is overpriced for this date in time which I believe is possible, in the long run though maybe not mass adoption and growth will validate the price given longer periods of time but at this point in time perhaps it is.
Currently you can say that the price includes a fairly decent premium, but that obviously only matters in the short term. If you look at the complete picture, then even $2000 will be nothing more than peanuts.
If you're purely long term minded as I am, then just sit back and enjoy seeing your coins grow in value throughout the years. At this point there is literally nothing that can stop Bitcoin from growing further, don't forget that.
