The term “HODLing,” crypto slang for buying and holding an asset for a long time, has historically been almost exclusively associated with bitcoin. and ether (ETH).
A trader has now applied the same long-term approach to perpetual futures linked to the euro-dollar pair (EUR/USD) listed on the Ostium decentralized exchange (DEX), which is based on Nasdaq data.
A trader has held a long EUR/USD position worth $1,139,490 for 400 days, Ostrium said on Tuesday. The bullish bet, expecting the euro to strengthen against the US dollar, was opened in early June 2025. EUR/USD was trading above 1.14 at the time of writing, virtually unchanged from where it was in June last year, but rose as high as 1.2082 in January this year.
On-chain forex trading offered by platforms such as Ostium, Gains Network, Synthetix, GMX and others remains a very small fraction of the traditional global forex market, whose daily trading volume exceeds $9 trillion.
However, this unique 400-day HODL on EUR/USD demonstrates that some traders are comfortable using blockchain rails and perpetual contracts to take leveraged positions in major traditional assets.
