Recently, many people have been asking about the logic behind Bitcoin's price fluctuations, so I’ve organized my observations.

It’s quite interesting—Bitcoin was hovering around $15,000 last year, and now it has risen to over $77,000, more than a fivefold increase in just over a year. What exactly is behind this? To understand the reasons for virtual currency price rises and falls, we need to look at both the supply side and the demand side.

On the supply side, Bitcoin’s total supply will always be 21 million coins, which is a hard rule written into the code. Over 20 million have already been mined, and the mining difficulty is increasing. More importantly, since April last year, the Bitcoin block reward has been halved; originally, 900 coins were supplied daily, now only 450. The supply is artificially limited, which is fundamentally a basis for price increases.

On the demand side, at the beginning of last year, the market suddenly saw 11 spot Bitcoin ETFs, which was a turning point. Institutional investors finally had a compliant way to enter, greatly increasing liquidity. Ordinary people also found it easier to trade through official channels, no longer needing to worry about security issues. With institutional backing, everyone’s expectations for Bitcoin’s price movements changed, and confidence significantly increased.

From a macro perspective, during times of global economic instability, Bitcoin, as a decentralized asset, has become a safe haven. Wealthy individuals and institutions have started allocating part of their assets into Bitcoin. Plus, countries’ attitudes toward cryptocurrencies are gradually softening, and policy directions are improving, all of which boost demand.

Regarding the reasons for cryptocurrency price fluctuations, market sentiment is also crucial. When optimism is high, FOMO (Fear of Missing Out) drives prices up; when pessimism takes over, panic selling causes prices to fall. On the technical side, factors like Bitcoin network security, hash rate, and mining difficulty adjustments all influence short-term trends. Recently, mining activity has become an important variable, as fluctuations in hash rate directly impact supply pace.

Additionally, the buying and selling behavior of large holders greatly influences market volatility. Sometimes, a single large transfer can trigger price swings. Policy changes also matter—news about regulation in a certain country can cause prices to plummet or surge instantly.

In essence, Bitcoin’s price movements are the result of a constant tug-of-war among supply, demand, sentiment, policy, and technology. There’s no fixed pattern; it all depends on which force is stronger at the moment. The reason Bitcoin has rebounded from last year’s lows to its current high is mainly due to tight supply and institutional entry—these are the two core drivers.

That said, the risks in cryptocurrencies are indeed significant, with high volatility. It’s important to do your homework before participating. I also keep an eye on related market trends and projects on Gate; if you’re interested, you can check them out yourself.
