Crazy or not there are still peopled investing even if the price is at the peak, I really think this is not the end of the increase of the price of bitcoin, and there are so much for us to go in a wide variety of value, and in my opinion if the last block isn't mined yet there is a possibility that the price would still increase.
I believe it as well, i believe that bitcoin price will increase in the future. So, it is a very good thing and decision when you hold your bitcoin and take it as your asset.
