We are expecting too much from bitcoin in just a short time of about 13years since it's creation. By logic bitcoin is just a teenager who has not yet attained the status of adulthood like the forex market for example, yet it has penetrate and saturate the financial market (global economy) becoming the talk of the town in the internet like it has been here 50 years ago.
In terms of the growth in price, I agree with your post that the expectation from Bitcoin is too high. However, in terms of impact, I feel the expectations is fine and a welcomed development. Remember that Bitcoin is an revolutionary innovation that was created to provide a better alternative to global financial system where accessibility, privacy and freedom are the focus. To this end, Bitcoin is yet to gain that adoption and acceptance considering that it is a revolution that usually changes everything within a short time.
The high expectations should be moderated so we can be able to appreciate the milestone growth bitcoin price has made. Commensurable with its age bitcoin price is doing great and only those who are not highly expectant setting their price scale at a great distance of 100k, 150k, 200k will care to appreciate the feat, some even predict as high as $1M in the next bull run and when the price doesn't go even close as expected they complain that the performance of bitcoin has been poor.
In terms of price growth, Bitcoin have done exceptionally good and have provided huge opportunity for people to profit. Those not satisfied with the growth of Bitcoin price probably came late to Bitcoin and are eager to see a repeat of the rapid growth Bitcoin have experienced since inception. I still believe that Bitcoin will still rise far more than it has done already but this will require some time.
