If we are in a bubble then it is just the start, we haven't reach the top yet. Of course every bubble is going to be burst, but then again, we are now in the levels that we haven't seen before obviously so we really don't know how far will this massive run will go, it could be a 6 year bubble or 3 year bubble so it's hard to predict now as we are just starting and it could end at $100k or even more.
