Someone recently asked me why Bitcoin has surged from $15,000 to $73,777 in just over a year, nearly a fivefold increase. Honestly, to understand the reasons behind the rise and fall of cryptocurrencies, you need to look at several key factors.

First is the change on the supply side. The total supply of Bitcoin is only 21 million coins, and this scarcity is coded into the system. Before April last year, about 900 coins could be mined each day, but starting from April last year, that was halved, and now only 450 coins enter the market daily. As supply decreases and demand increases, the price naturally goes up.

More importantly, the approval of spot ETFs early last year changed the entire game. Eleven Bitcoin ETFs were launched at once, making it easier for retail investors and institutional funds to participate. This not only increased liquidity but also provided endorsement from traditional financial markets. Once institutions start taking this asset class seriously, retail confidence also rises, and demand naturally surges.

But the reasons for cryptocurrency price fluctuations go far beyond that. Market sentiment swings are also crucial. When everyone is optimistic about the future, buying pressure floods in, pushing prices higher; conversely, any negative news can quickly spread panic. Additionally, uncertainties in government attitudes toward cryptocurrencies, changes in mining dynamics, and even global macroeconomic conditions can have tangible impacts on Bitcoin’s price movements.

I’ve noticed that during economic turmoil or financial market instability, Bitcoin is often seen as a safe-haven asset, which also boosts demand. Meanwhile, large investors entering or exiting can cause significant short-term price volatility. That’s why the reasons behind crypto price swings are so complex—supply, demand, policies, sentiment, technological progress—these factors intertwine, and there’s no single explanation.

Ultimately, Bitcoin, as a representative of decentralized assets, reflects the evolving perception of this new asset class. From mining recovery to hash rate changes, from policy attitudes to institutional participation, every variable influences short- and medium-term trends. So, to understand the reasons behind crypto price movements, you need to keep a close eye on the market and see how these factors interact.

However, this volatility also means risk. Before participating in Bitcoin trading, it’s essential to fully understand your risk tolerance, make rational decisions, and not get overwhelmed by short-term fluctuations.
