Key takeaways
- Bitcoin has historically moved by large percentages within days or weeks, in both directions — this isn't unusual behaviour for the asset.
- Investor sentiment, liquidity conditions, leveraged trading positions and macroeconomic news all contribute to short-term price swings.
- Long-term price direction and short-term volatility are separate questions — an asset can be volatile regardless of its longer-term trend.
- Only ever put in money you could afford to lose entirely, given how genuinely unpredictable short-term moves are.
- This article doesn't predict where the price is headed — nobody can reliably do that, and be wary of anyone who claims otherwise.
Anyone new to Bitcoin is usually warned it's "volatile" — but that word undersells how large and how fast the swings can actually be. Understanding what actually drives that movement is more useful than any single price figure.
How large are we talking?
Bitcoin has moved tens of thousands of dollars within a single year on multiple occasions, including periods where it traded 30% or more below a recent high. In early September 2026, Bitcoin was trading in the high US$70,000s to around US$79,000 depending on the day — a range that itself shifted noticeably within just that first week of the month. The exact number matters far less than the pattern: meaningful moves, in both directions, over short periods, are normal for this asset, not a sign that something has gone wrong.
What actually drives short-term swings
- Investor sentiment — Bitcoin is heavily influenced by how traders collectively feel about risk at any given moment, more so than assets with steadier institutional ownership.
- Leveraged positions — large amounts of borrowed-money trading can amplify moves in either direction as positions are forced to close.
- Liquidity and volume — thinner trading periods can see outsized price moves on comparatively modest buying or selling.
- Macroeconomic and regulatory news — announcements affecting the broader financial system or crypto-specific regulation can move price quickly.
Volatility vs long-term direction — different questions
Whether Bitcoin is "a good long-term investment" and whether it's "volatile in the short term" are separate questions with separate answers. An asset can be extremely volatile day-to-day while its long-term trajectory is something else entirely — and the reverse can also be true. Don't let short-term price swings alone tell you what to conclude about the longer term, and don't let a calm week convince you the volatility is gone.
What this means practically
If you're considering buying Bitcoin, plan around the volatility rather than being surprised by it: decide in advance how much you're comfortable holding through a significant drop, and avoid checking the price so often that ordinary swings become a source of stress. Many beginners find it easier to start with a smaller amount and get comfortable with the volatility before considering a larger position.
Only ever invest money you could afford to lose entirely. Past price behaviour, including everything described in this article, is not a reliable guide to future performance.
Where this fits with buying
If you've decided you understand the risk and want to go ahead, our step-by-step guide to buying Bitcoin in Australia covers the practical process. This article, by contrast, is specifically about understanding the risk itself — not a recommendation to buy, hold or sell at any particular time.
