When does crypto winter start & end?

In the ever-evolving world of cryptocurrency, the concept of "crypto winter" often looms large in the minds of investors and enthusiasts. It represents a period of downturn and reduced interest in digital currencies, typically marked by decreasing prices, diminished trading volumes, and less overall buzz surrounding the market. However, pinning down an exact start and end date for such a phenomenon is challenging, given the decentralized and volatile nature of cryptocurrencies. So, the question arises: When does crypto winter truly begin, and how do we know when it ends? This is not a question with a simple, universal answer, as the market dynamics and external factors influencing cryptocurrencies vary from one period to another. But it's an important query that demands exploration, given its profound impact on investors' portfolios and the future trajectory of the industry.
