How to short Bitcoin
Written by an ex-institutional trader. What shorting Bitcoin means, how to do it in Australia with crypto CFDs (shown with a diagram), how leverage works, the real risks of going short, and how to start safely with an ASIC-regulated broker.
Direct answer
Shorting Bitcoin means selling it first to profit if the price falls, and the simplest way to do it in Australia is with a crypto CFD through an ASIC-regulated broker. Because a CFD never requires you to own the coin, you can open a sell (short) position directly: if Bitcoin falls, you buy back lower and keep the difference; if it rises, you lose. It lets traders profit in a falling market and hedge existing holdings.
Shorting carries the same volatility risk as going long, plus a structural one: when you are short, a rising price works against you, and crypto can rally hard and fast. ASIC caps crypto CFD leverage at 2:1 and provides negative balance protection so you cannot lose more than your account, but a short can still be very costly in a sharp rally or short squeeze. A stop loss on every short and small position sizing are essential, not optional.
What shorting Bitcoin means
Shorting Bitcoin means profiting from a falling price by selling first and buying back later at a lower price. It is the opposite of the usual buy-low-sell-high: you sell high first, then aim to buy back low, and pocket the difference. It lets traders make money when they expect Bitcoin to fall, and to hedge coins they already hold against a downturn.
The catch is that you cannot easily sell something you do not own. That is where the crypto CFD comes in: because a CFD only tracks the price and never requires you to own the coin, you can open a short position directly, as simply as clicking sell instead of buy.

How to short with a CFD
With a crypto CFD, shorting Bitcoin is mechanically simple. You open a sell position at the current price. If Bitcoin falls, you close by buying back lower, and the difference is your profit. If it rises, you close at a loss.
The steps with an ASIC-regulated broker are: open and fund a CFD account, select Bitcoin, choose sell rather than buy, set your position size and a stop loss above your entry, and place the trade. The stop loss is non-negotiable on a short, because the thing that hurts you, a rising price, can move fast.
Leverage and shorting
Crypto CFDs are leveraged, so a short uses margin: you put up a fraction of the position value and the broker funds the rest. At the ASIC retail cap of 2:1, a 500 dollar deposit controls a 1,000 dollar short. This magnifies both the profit if Bitcoin falls and the loss if it rises.
That 2:1 cap is the lowest ASIC applies to any asset class, set deliberately low because crypto is so volatile. Even so, a leveraged short can move quickly against a small balance, so sizing the position to risk only a small percentage per trade, with the position size calculator, matters even more on a short than a long.
The risks of going short
Shorting carries a risk profile that longs do not. When you go long, the most a price can fall is to zero, so the loss is capped. When you short, a rising price works against you, and in theory a price has no ceiling, so losses can grow as it climbs. Crypto makes this sharper, because rallies and short squeezes can spike the price violently.
Two things keep this in check in Australia. First, a stop loss caps the loss on any short at a level you set. Second, ASIC requires negative balance protection, so you cannot lose more than your account balance even in an extreme move. Neither removes the risk; both make it survivable. The practical rule is that shorts demand even stricter stop-loss discipline than longs, because the move that hurts them can be fast and large.
How to start
A sensible order before shorting real money:
- Learn the fundamentals. Understand crypto CFDs, leverage, margin and the stop loss first.
- Practise on a demo account. Open and close short positions with virtual money to learn the mechanics at no risk.
- Choose an ASIC-regulated broker. Plus500, Pepperstone and AvaTrade offer crypto CFDs to Australians, compared in the crypto CFD trading guide.
- Start small, always use a stop. Risk a small fixed percentage per trade and place a stop loss above your entry on every short.

Frequently asked questions
How do you short Bitcoin?
The simplest way to short Bitcoin in Australia is with a crypto CFD through an ASIC-regulated broker. You open a sell (short) position rather than a buy: if Bitcoin's price falls, you can close by buying back lower and keep the difference as profit; if it rises, you lose. Because a CFD never requires you to own the coin, opening a short is as simple as clicking sell instead of buy. You set a stop loss above your entry to cap the loss if the price rises against you.
What does shorting crypto mean?
Shorting crypto means betting that the price will fall, by selling first and aiming to buy back later at a lower price. The difference between your higher sell price and lower buy-back price is your profit. With a crypto CFD you can do this without owning the coin: you simply open a sell position. Shorting lets traders profit in falling or bearish markets and hedge a portfolio of coins they hold, which is impossible if you can only buy and hold.
Can you short Bitcoin in Australia?
Yes. You can short Bitcoin in Australia through crypto CFDs offered by ASIC-regulated brokers such as Plus500, Pepperstone and AvaTrade. ASIC caps crypto CFD leverage at 2:1 and requires negative balance protection, so you cannot lose more than your account balance. Shorting is legal and straightforward through a regulated broker; the constraint is risk, not legality, because a short loses if the price rises and crypto can rally sharply.
Is shorting Bitcoin risky?
Yes, shorting Bitcoin is high-risk. It carries the same volatility risk as going long, plus the structural feature that a rising price works against your position, and crypto can rally hard and fast, including short squeezes that spike the price. In theory a short's loss grows as the price rises, which is why a stop loss is essential. In Australia, ASIC negative balance protection means you cannot lose more than your account balance even in an extreme move, but a short can still produce a large, fast loss without disciplined risk control.
What is the risk of shorting versus going long?
When you go long, your maximum loss is capped because a price can only fall to zero. When you short, a rising price works against you and, in theory, has no ceiling, so the risk profile is different: losses can grow as the price climbs. In practice, a stop loss caps the loss on any short, and in Australia negative balance protection prevents your account going below zero. The practical lesson is that shorts demand even stricter stop-loss discipline than longs, because the thing that hurts them, a rally, can be violent in crypto.
How does leverage work when shorting Bitcoin?
With a crypto CFD, leverage lets you open a short worth more than the margin you put up: at the ASIC retail cap of 2:1, a $500 deposit can control a $1,000 short position. This magnifies both profit and loss relative to your deposit. Because crypto is so volatile, even the 2:1 cap, the lowest ASIC applies to any asset class, makes shorts move quickly against a small balance. Sizing the position so you risk only a small percentage per trade is what keeps leverage from turning a normal rally into a damaging loss.
