The ratio of options / ultimately represents the proportion of interests open in options of options compared to term contracts. A higher ratio indicates greater importance on the trading of options than long -term trading.
The Bitcoin Option / Futures / Future Open Interest ratio has always exceeded that of Ethereum, which raises questions about the underlying drivers. Coinglass data show that the Bitcoin ratio goes from 57.80% to 69.60% since early March, while Ethereum report increased more and more than 26.9% to 32.98%.
This gap, with the Bitcoin ratio almost double that of Ethereum every day, suggests a stronger preference for options on term contracts among Bitcoin traders. To understand why, we can examine the OI options and price performance for both assets during this period alongside wider market trends.

First, the activity of the optional scale provides a context. Bitcoin OI options increased from $ 28.09 billion on March 2 to $ 34.82 billion on March 6, an increase of 24%.

Ethereum OI options, while increasing 27% of $ 5.10 billion to $ 6.47 billion, remain 5 to 6 times smaller in absolute terms. This disparity reflects the largest market capitalization in Bitcoin, which historically works 3 to 5 times higher than that of Ethereum, attracting more volume of trading and liquidity. Greater liquidity attracts both institutional traders and retail trade to Bitcoin options, often used for the coverage or expression of price movements on a more established market. Authorized participants of Bitcoin ETF spots use both future and options to generate income while minimizing the risk in the facilitation of Bitcoin baskets to make the ETF inventories.

Price performance in March highlights the divergence. Bitcoin’s Price Increases from $ 84.413 on March 1 to $ 90.624 on March 6, A 7.4% Gain, DESPITE VOLLITILITY with a peak at $ 94.238 on March 3 and A DIP TO $ 86.212 on March 4. Starting at $ 2.216, Etherreum’s Price $ 2.297 by March 6, A 3.7% Gain, goal experience in Sharper Drop from $ 2.519 on March 2,145 $ on March 3. Bitcoin’s stronger net gain and higher volatility align with its growing options / term contracts on the ratio, because traders probably use options to capitalize or hide against these oscillations.
The more modest price movement of Ethereum and the absolute lower price can reduce the perceived need for options based on options, now its lower ratio despite the stable options on growth.
Market size and liquidity play an important role in the higher Bitcoin ratio. With a larger market, Bitcoin naturally sees more absolute negotiation activity, supporting a market for robust options. Higher liquidity makes bitcoin a favorite choice for traders who seek to manage risks, mainly thanks to options offering flexibility on future. With a smaller market, Ethereum sees greater dependence on the future for directional speculation, reflecting its less developed derivative ecosystem.
The cover request also contributes away. With swings like the increase of 11.7% and a drop of 8.5%, the volatility of Bitcoin prices encourages traders to promote risk management options, in particular the dominant role of Bitcoin in the cryptographic space. This is obvious in the options for recovery of growth monitoring prices after March 4. The volatility of Ethereum, including a drop of 14.9%, is notable but less impacting in absolute terms because of its lower price, which leads to a drop in options / term contracts on merchants, traders lean towards term contracts.
Institutional participation is still expanding the ditch. Bitcoin experienced greater institutional adoption, in particular since the approval of Bitcoin Spot ETF in 2024, strengthening its derivative market. Institutions often prefer the options for capital efficiency and flexibility, increasing the OOi options / future Bitcoin ratio. Ethereum, while benefiting from trading by Eth Spot ETH since mid-2024, has been late.
The lower performance of ETFE Ethereum, with annual yields ranging from -1.78% to -36.48%, signals the confidence of lower investors compared to Bitcoin ETF, which, despite negative ytd yields, manage larger asset bases and higher commercial volumes 376.60 million dollars.
This underperformance in ETHEREUM probably discourages institutional adoption, because institutions prioritize assets with stronger validation and liquidity of the market. The reduction of institutional interest in ETHEREUM limits the growth of its market market, because institutions are of the main engines of the activity of options for coverage and speculation. Consequently, the Options / Futures ratio of Ethereum remains lower, reflecting a less mature derivative market compared to that of Bitcoin.
Finally, market maturity gives Bitcoin an advantage. Bitcoin has a longer history and a more developed option market. Traders consider Bitcoin options as a reliable tool for speculation or risk management, while the Ethereum options market, always maturing, sees less activity compared to future.
The data of March 2025 support this, with the higher prices of Bitcoin prices, the larger options market and higher institutional support stimulating its higher options / future ratio. Despite the growth of OI options, Ethereum remains constrained by its small market and lower institutional adoption, keeping its ratio lower and highlighting the domination of bitcoin in the cryptographic derivative market.
