- Swing trader 0x5d2 opened a roughly $63.6M Bitcoin short near the end of October and is sitting on about $12.5M in realized and unrealized gains as of late December 2025.
- The position has generated about $9.6M in funding fees alone, thanks to persistent positive funding rates that paid the short over roughly two months.
- The whale also holds around $3.5M in BTCB on BNB Chain, indicating additional Bitcoin-linked exposure across networks beyond the main short.
The ever-shifting landscape of cryptocurrency markets, blockchain analytics firm Arkham Intelligence has spotlighted a savvy swing trader making waves with a calculated Bitcoin short. Dubbed “0x5d2” based on the wallet address 0x5D2F4460Ac3514AdA79f5D9838916E508Ab39Bb7, this entity has amassed $12.5 million in combined realized and unrealized profits from a position initiated at the end of October.
Funding Fees Drive Most of the Profit
The trade involved shorting Bitcoin equivalent to $63.6 million in value, betting on a price decline. As of Arkham’s latest report on December 23, 2025, the hold has proven prescient, capitalizing on BTC’s recent downward pressure. What’s particularly noteworthy is the $9.6 million generated purely from funding fees—a mechanism in perpetual futures contracts where long positions pay shorts during bullish sentiment. This whale’s patience has turned time into an ally, as positive funding rates have persisted, rewarding the short seller for maintaining the position over two months.
Beyond the headline-grabbing BTC short, the wallet reveals a diversified portfolio. The trader holds $3.5 million in BTCB, a tokenized version of Bitcoin on the BNB Chain, suggesting a strategic hedge or cross-chain play. Arkham’s visualization tools depict a web of interactions with major exchanges like Bybit, Binance, and OKX, alongside tokens such as USDT and various DeFi protocols. This connectivity underscores the trader’s integration into the broader Web3 ecosystem, from centralized exchanges to decentralized finance.
Active Across Major Exchanges and DeFi
This revelation comes at a pivotal time for Bitcoin, which has faced headwinds from regulatory scrutiny, macroeconomic shifts, and seasonal market lulls heading into the holidays. While retail traders grapple with volatility, whales like 0x5d2 demonstrate the edge gained through leverage and timing. Funding rates, often overlooked by novices, highlight how perpetuals can amplify gains beyond mere price movements—in this case, contributing nearly 77% of the total profit.
For the crypto community, this serves as a reminder of the high-stakes game in derivatives trading. Shorting BTC requires nerves of steel, especially in a market prone to sudden reversals. Yet, with tools like Arkham providing transparency, everyday users can track these giants and glean insights. As we close out 2025, will this whale close the position for a festive windfall, or ride the short further? Market watchers are tuning in.
