Summary
- A trader on the decentralized exchange Ostium has held a $1.14 million long position in EUR/USD perpetual futures for 400 days, applying a bitcoin-style HODLing strategy to forex.
- The position has incurred an annual holding cost of about 2.3% through predictable rollover fees rather than traditional crypto funding rates.
- Ostium and similar platforms still represent a tiny share of the more than $9 trillion-a-day global FX market.
The term “HODLing," crypto slang for buying and holding an asset for a long time, has historically been associated almost exclusively with bitcoin BTC$62,818.33 and ether (ETH).
One trader has now applied the same long-term approach to perpetual futures tied to the euro-dollar pair (EUR/USD) listed on the decentralized exchange (DEX) Ostium, which is powered by Nasdaq data.
A trader has held a long position in EUR/USD worth $1,139,490 for 400 days, Ostrium said on Tuesday. The bullish bet, expecting the euro to strengthen against the U.S. dollar, was opened around early June 2025. EUR/USD traded above 1.14 as of this writing, largely unchanged from where it was in June last year, but it did rise as high as 1.2082 in January this year.
Onchain FX trading offered by platforms such as Ostium, Gains Network, Synthetix, GMX, and others remains a very tiny fraction of the global traditional FX market, which sees daily trading volume exceeding $9 trillion.
Nevertheless, this single 400-day HODL on EUR/USD demonstrates that some traders are comfortable using blockchain rails and perpetual contracts to take leveraged positions on major traditional assets.
Ostium highlighted that the position incurred a holding cost of approximately 2.3% per year through predictable rollover fees.
Unlike typical crypto perpetual futures, which use funding rates, or periodic payments between longs and shorts to keep the contract price aligned with spot, Ostium uses volatility-based rollover fees for FX pairs, modeled more closely after traditional forex swap/rollover mechanics.
These costs are generally more stable and predictable.It remains to be seen whether this example will inspire more long-term, on-chain trading of traditional assets.
