The cryptocurrency market has experienced several major collapse events in history. Here are some notable years:

1. 2013: By the end of 2013, the price of Bitcoin had risen to a record high of around 1,200 USD before plummeting to about 200 USD by mid-2015. This volatility was mainly due to bans and regulations from governments.

2. 2017-2018: After a strong price surge at the end of 2017, when the price of Bitcoin reached nearly 20,000 USD, the market experienced a significant collapse in early 2018, leading to the price of Bitcoin dropping to around 3,000 USD by the end of 2018. This is considered a "cryptocurrency winter."

3. 2020: Following a strong price increase in early 2020, the price of Bitcoin unexpectedly plummeted in March due to the impact of the COVID-19 pandemic, but then recovered and reached a record high by the end of the year.

4. 2022: The crypto market continued to struggle with the collapse of several major projects and significant price corrections. For example, the price of Bitcoin dropped from around 69,000 USD in November 2021 to about 20,000 USD by mid-2022.

In 2025, the market collapsed significantly due to the impact of trade war tariffs imposed by President Trump. Also, don't worry too much because this is not the first collapse, and we can also see that regardless of what happens, the market always tends to grow over the long term.

These events are often accompanied by high interest rates, the impact of global economic factors, and instability in government regulations. The crypto market is very volatile, and these collapses are part of its development and maturation process.
