In recent weeks, retail investors (who also happen to be the core fans of Bitcoin) have been in an all-out war with short-sellers -- i.e., investors who profit when the price of a security falls. Some even view short-sellers as evil. But short-selling is a natural part of the investing cycle that helps lead to price discovery.
Bitcoin is really difficult to short-sell on most platforms, which means we're not getting anywhere near a true price discovery. This market inefficiency is one of the reasons Bitcoin is so exceptionally volatile.
