I guess that is because we are very interested on how does the money fluctuate and the way we understand the current event with regards to Bitcoin impress us a lot. I took economics last semester in our school and I can say beyond any market and even on a daily living we can say that economics is really applicable even in a simple debt and hoarding money it affects the entire system of monetary fluctuation which I can really impress me since the direct application of the things we learnt is so much visible and somehow I cam apply these learning here in understanding Bitcoin.
