Percentage-based cryptocurrency pricing can cause trading costs to rise automatically as Bitcoin becomes more expensive, creating a significant difference between broker fee models, according to RationalFX research comparing Bitcoin pricing across major CFD providers.
Study Compares 10 Major Brokers
The study examined 10 brokers: IG, Pepperstone, Plus500, eToro, IC Markets, Interactive Brokers, FP Markets, Fusion Markets, XTB and Capital.com and compared their costs across Bitcoin as well as EUR/USD, gold, the NASDAQ 100 and Apple share CFDs.
Percentage-Based Pricing Models
RationalFX found that eToro, Interactive Brokers and XTB use percentage-based pricing models for Bitcoin rather than relying solely on fixed or floating spreads expressed in dollar terms. Under a percentage structure, the monetary value of the charge increases as the price of Bitcoin rises, even if the percentage itself remains unchanged.
Cost Comparison at Current Bitcoin Prices
Using a Bitcoin price of $68,496.93 on February 10, 2026, the research found eToro had the highest total spread cost in the comparison, reflecting its 1% pricing model. By contrast, IC Markets and Pepperstone were identified as having particularly tight market-driven Bitcoin spreads that did not scale as aggressively with the underlying asset price.
This means the same fee structure can produce a very different dollar cost at different Bitcoin prices. Percentage-based pricing may therefore become increasingly important to traders when the asset experiences a sustained increase in market value.
Overnight Financing Costs Add Up
The spread or transaction charge is not the only consideration. RationalFX describes cryptocurrency as potentially one of the most expensive asset classes for leveraged overnight positions. Depending on the broker and product structure, financing can be applied more frequently than once per day, allowing costs to build quickly when a leveraged crypto CFD remains open for an extended period.
Leveraged CFDs vs. Owning the Underlying Asset
The report also distinguishes between leveraged CFD exposure and owning an underlying cryptocurrency. For example, it notes that eToro does not impose overnight fees on non-leveraged Buy positions involving real crypto assets, whereas leveraged crypto CFD positions incur financing costs.
That distinction is important because two positions linked to the same Bitcoin price can have different cost structures depending on whether the trader owns the underlying asset or uses a leveraged derivative.
Why Direct Comparisons Are Difficult
It also makes direct broker comparisons more difficult than simply placing quoted Bitcoin charges side by side. A percentage fee, a market-driven spread and an overnight funding rate respond differently to changes in the underlying asset and to the way a position is held. Traders therefore need to compare like with like before deciding which structure is cheaper.
Key Takeaway for Crypto Traders
RationalFX’s findings therefore show why cryptocurrency traders should look beyond a single advertised spread or commission figure. The pricing model itself, Bitcoin’s market value, use of leverage and the length of time a position remains open can all influence the total amount paid.
