Your article seems interesting and I guess you are right that bitcoin is something people buy and expect to grow in price in the future. It's a shame that this is the case, though, because it was created for transactions without trust to third parties. I know it turned out that sometimes bitcoin is incapable to perform fast enough when there's a big amount of simultaneous transactions and the fees are sometimes quite high for small purchases, but there are still many cases in which it could be used perfectly rather than stored as something of high value.
