Most leveraged traders lose because leverage turns ordinary price noise into account-ending moves, while fees and funding are charged on the full position size rather than on the margin. At 10x, a 1% move is 10% of your margin, a routine 9.5% swing liquidates you, and fees for a single round trip can cost about 1% of your margin. Leverage itself is just a tool; the losses come from using it to make positions far bigger than a stop-based plan allows.
There is public evidence that leveraged retail trading is hard. In the European Union and the United Kingdom, brokers offering contracts for difference (a similar leveraged product) must show the percentage of their retail accounts that lose money, and the published figures typically show that most do. The math below explains why.
The math of a 10x position
You post $1,000 of margin at 10x on BTC. Your position is worth $10,000.
| BTC price move | Profit or loss | Change in your margin |
|---|---|---|
| +5% | +$500 | +50% |
| +1% | +$100 | +10% |
| -1% | -$100 | -10% |
| -3% | -$300 | -30% |
| -5% | -$500 | -50% |
| about -9.5% | liquidated | about -100% |
Bitcoin's ordinary daily range is often several percent, and altcoins move more. That means on a quiet day your 10x position can swing 30% of your margin, and on a busy day it can be gone. On 12 March 2020, Bitcoin fell by more than a third in a single day. Any 10x long held through that fall without a stop was liquidated, and many stops filled far below their trigger.
Costs are charged on the full position
Fees and funding apply to the $10,000 position, not your $1,000:
Example
Taker fee 0.05% per side. Opening costs $5 and closing costs $5, so one round trip costs $10, about 1% of your margin. A trader who makes 20 round trips a month pays about $200 a month, 20% of the margin, before winning or losing a single trade.
Example
Funding at the common baseline of 0.01% per 8 hours costs $1 per payment, $3 per day and about $90 over 30 days, which is 9% of the margin each month if you hold a long through a typical bullish market.
Those costs mean you have to be right more often just to stay level.
Example
You aim for +3% (+$300) with a stop at -3% (-$300), paying $10 in fees per trade. A win nets $290 and a loss costs $310. The win rate you need to break even = 310 / (290 + 310) = 51.7%. Most traders cannot reliably win more than half of symmetric trades, so they slowly bleed even before mistakes.
Losses are harder to recover than gains
| Drawdown | Gain needed to recover |
|---|---|
| -10% | +11.1% |
| -25% | +33.3% |
| -50% | +100% |
| -75% | +300% |
| -90% | +900% |
High leverage produces large drawdowns quickly. After two bad 10x trades taking -30% each, the account is at 0.7 x 0.7 = 49% of its start, and it needs to more than double to recover.
The real problem: sizing by margin
Compare two traders, each with a $1,000 account:
Trader A puts the whole $1,000 as margin at 10x on BTC and sets no stop: a $10,000 position. A 9.5% fall wipes out the entire account. A 3% fall costs $300, 30% of everything.
Trader B risks 1% of the account, $10, with a stop 3% below entry. Position size = 10 / 0.03 = $333. Trader B uses 2x leverage, so margin is only $167, and keeps the rest of the money in a wallet off the exchange. The worst planned loss is about $10, and liquidation is about 50% away, far beyond the stop.
Both traders "use leverage". Only Trader A uses it to multiply risk. Trader B uses it to post less collateral, which is what leverage is actually good for. This is why Position Sizing and the 1% Rule comes before futures in this course.
The behaviour leverage invites
The math is only half of it. Leverage also encourages the habits that destroy accounts:
- Over-trading: large swings feel exciting, so traders take more trades, paying more fees.
- No stop, or a moved stop: "It will come back" is fatal when liquidation is 9.5% away.
- Adding margin to a loser to avoid liquidation, which increases the amount at risk.
- Revenge trading: doubling leverage after a loss to win it back quickly.
- Holding through funding: keeping a leveraged long for weeks in a market with high funding, paying a large share of margin to other traders.
How to use leverage, if you use it at all
- Size from the stop. Calculate the position first; let leverage only reduce the margin.
- Keep leverage low. For most planned trades, 1x to 3x provides all the capital efficiency you need.
- Use isolated margin and keep only active-trade money on the futures wallet.
- Set a reduce-only stop immediately when the position opens.
- Check costs. Add fees and expected funding to your risk before entering.
- Cap daily losses. Stop trading for the day after a set loss, for example 2% of the account.
Risk
If you notice that you are increasing leverage to make losses back, stop trading futures entirely for a set period. Many traders who blow up do so in the days after a big loss, not on their first trade.
Pro note
Leverage does not change a strategy's expectancy per unit of risk. If a strategy loses money at 1x, it loses money faster at 10x. If it has a small edge, high leverage increases the chance that a normal losing streak ends the account before the edge can show; see Risk of Ruin.
Next, look at another place where high yields hide high risks: DeFi and Staking Risks.
Key takeaways
- At 10x, every 1% price move is 10% of your margin, and a 9.5% move against you ends the trade.
- Fees and funding are charged on the full position, so at 10x a single round trip can cost about 1% of your margin.
- Costs raise the win rate you need: a 1:1 trade at 10x with typical fees needs more than 51% wins just to break even.
- The deadly mistake is sizing by margin instead of by stop; leverage then multiplies the loss instead of saving capital.
- If you use leverage at all, size from the stop, keep it low, use isolated margin and keep most money off the exchange.
