Black Swan Event

A Black Swan event is a term popularized by the finance professor and former Wall Street trader Nassim Nicholas Taleb. It refers to an extremely rare event that has severe, often catastrophic, consequences. These events are characterized by their extreme rarity, severe impact, and the widespread insistence they were obvious in hindsight.

When applied to the field of cryptocurrencies, a Black Swan event would typically refer to a very rare and unexpected event that significantly impacts the value or functionality of cryptocurrencies. It could be a technical issue, like a flaw in a cryptocurrency’s algorithm that allows it to be hacked, or a social one, like a sudden governmental ban of cryptocurrencies in a major economic power.

A notable example is the 2010 incident in the Bitcoin network known as “value overflow incident,” which was a major bug that created 184 billion bitcoins. It was a black swan event because it was unexpected, had a massive impact (potentially disastrous for Bitcoin), and in hindsight, the bug was obvious.

Another hypothetical example could be a sudden decision by a large country like China or the US to outright ban all cryptocurrency transactions. This would have a major impact on the value of all cryptocurrencies and would come as a shock to most people.

Keep in mind, the unpredictability and rarity are what make an event a “Black Swan.” So it’s often hard to predict what the next one might be, and even harder to prepare for it.
