I remember hearing that people took out mortgages to buy bitcoin, and this was, as you said, when it was about 17k. I feel bad for them, but I also am at a loss to understand why someone would go to such extremes to invest in something which at the time and still isn't 100% going to stick around for the long-term!

I followed you since from reading this post I believe you have a very common sense view on the matter :).
