Recently, many people have been asking why Bitcoin is so volatile, skyrocketing from $15,000 to over $126,000 in just over a year, which is indeed a bit crazy. To understand the principles behind the rise and fall of virtual currencies, first you need to know what the fundamentals of Bitcoin are.

Bitcoin's supply is fixed, with only 21 million coins in total, which is the most basic scarcity. Currently, over 20 million coins are in circulation worldwide, and the daily new supply was halved in April 2024, from 900 coins down to 450 coins, directly affecting the supply and demand relationship. When supply decreases and demand increases, prices naturally go up.

A major turning point in early 2024 was the launch of Bitcoin spot ETFs, with 11 related fund products appearing on the market all at once. What does this mean? Ordinary investors and institutional investors can now enter more easily, significantly increasing liquidity, and the backing of institutions also boosts market confidence in digital assets. As demand rises, prices follow, which is the most direct principle behind virtual currency price fluctuations.

But price volatility isn't just about supply and demand. Policy attitudes have a big impact; when government regulatory stances change, the market reacts immediately. The economic environment is also a key factor—when global financial markets are turbulent, some people see Bitcoin as a safe haven asset, which can boost demand. Conversely, if market sentiment turns pessimistic and investor confidence drops, prices can fall rapidly.

Technical factors are also worth paying attention to—upgrades in Bitcoin's security, scalability solutions, privacy protection technologies—all can influence investor expectations. Additionally, mining dynamics are an often overlooked variable; whether hash power recovers or diminishes can significantly impact short- to medium-term price trends. The buying and selling behavior of large investors can also trigger short-term fluctuations; their actions often sway the entire market.

In essence, the principles behind the rise and fall of virtual currencies are the complex interactions of these factors. Market supply and demand, policy environment, investor sentiment, macroeconomics, technological progress, security issues—all are at play simultaneously, and their relationships are constantly changing, which makes Bitcoin's price movement so difficult to predict.

If you want to participate in this market, it’s recommended to thoroughly understand how these factors operate and closely monitor policy and market dynamics. Bitcoin investment carries significant risks; prices can be highly volatile, so decisions should be based on your own risk tolerance.
