On April 26th, 2023, the cryptocurrency market experienced a significant decline in the price of Bitcoin. The reason behind the crash is still a topic of debate, but there are several factors that could have contributed to the market's reaction. One of the most critical factors is the bug-fixing event by Arkham Intelligence, a crypto-related alert provider.

Arkham Intelligence had just fixed a bug related to Bitcoin alerts, which made them stop sending notifications to a particular subset of users. However, the fix had unintended consequences. Users who had previously set alerts on Bitcoin transactions above $10,000, with keywords like "Mt Gox" and "US Gov," began receiving these alerts again. This led to further speculation in the crypto community, with some arguing that the notifications triggered panic selling and contributed to the Bitcoin price crash.
