Highlights
- A trader tracked by Arkham, labeled 0x15a, is sitting on a combined $21.78 million in unrealized profit across leveraged bitcoin and ethereum longs.
- The trader opened a $77.1 million BTC long at 40x leverage about a month ago, entering near $62,354, and is now up $14.78 million on that position alone.
- A separate $24.6 million ETH long at 20x leverage has added another $7 million in gains as both assets have recovered.
- The entry timing lines up closely with bitcoin's own recent low, raising the question of whether the trader called the bottom of the latest drawdown.
Blockchain intelligence platform Arkham flagged a trader it labeled 0x15a as sitting on a combined $21.78 million in unrealized profit across two leveraged positions in bitcoin and ether. The larger of the two, a $77.1 million bitcoin long opened at 40x leverage roughly a month ago with an entry price of $62,354, has generated $14.78 million in gains as bitcoin has since climbed back above $77,000. The trader also holds a $24.6 million ether long at 20x leverage, which Arkham said is up $7 million. Both positions were opened close to what has turned out to be a local bottom for both assets, prompting the question of whether the trader timed the low almost exactly.
A Position Opened Into the Bottom
The timing lines up with a turbulent month for both assets. Bitcoin crashed below $77,000 after a hawkish Jackson Hole speech from Fed governor Kevin Warsh roiled risk markets, and the coin fell further still before finding a floor near the low-$60,000s — almost exactly where 0x15a's BTC long was opened. From there, bitcoin clawed back its losses and eventually reclaimed $80,000 as rate-hike bets eased, before slipping back toward $77,000 this week amid a fresh bout of oil-driven inflation worry. That round trip is exactly the kind of volatility a 40x leveraged position is built to exploit — and just as easily built to be wiped out by, had the entry been mistimed by even a few percentage points given how thin the liquidation buffer becomes at that leverage level.

Ether has traced a similar arc over the same stretch, and 0x15a's 20x leveraged position there has added a further $7 million to the trader's total. Combined, the two positions represent over $100 million in notional exposure controlled with a comparatively small amount of posted margin, a structure that magnifies both the size of the win being celebrated here and the size of the loss that would have followed had bitcoin and ether kept falling instead of rebounding.
What This Says About the Broader Market
Leveraged positions of this size function as a kind of real-time sentiment gauge for the broader market, particularly when they're placed at extremes rather than into an already-established trend. A trader willing to put on $77 million of 40x-leveraged bitcoin exposure near a local low is making a much more concentrated bet than the average spot buyer, and when that bet pays off publicly on a platform like Arkham, it tends to reinforce the narrative that the bottom is in — whether or not that's actually true. That reflexive effect matters heading into a week when markets are digesting a fresh CPI report and elevated oil prices, both of which are pushing in the opposite direction of the rate-cut optimism that fueled bitcoin's climb back to $80,000.
It's also a reminder of how leverage has become a defining feature of this cycle's price action. With ether options traders buying more calls than bitcoin's own ahead of Fed week, and whales like 0x15a running triple-digit notional exposure on comparatively modest capital, a large share of the recent volatility in both assets is being amplified by derivatives positioning rather than spot demand alone. That makes rallies sharper on the way up and drawdowns sharper on the way down, and it raises the stakes for whatever the Fed and incoming inflation data do next, since a hawkish surprise could just as easily turn 0x15a's current gain into the kind of forced liquidation that has hit other high-leverage traders this cycle.
What to Watch Next
The clearest next test for 0x15a's thesis is how bitcoin and ether react to this week's CPI print and whatever signal the Fed sends at its next meeting: a dovish surprise would likely extend both positions' gains, while a hawkish one — especially paired with oil prices staying elevated — could quickly erase them given the leverage involved. Whether the trader closes out and realizes the current $21.78 million gain or lets both positions ride into the Fed decision will itself be a signal other market participants are likely to watch, since Arkham's public tracking means 0x15a's next move won't stay private for long. Either way, the position stands as one of the more visible bets so far that the worst of this drawdown cycle is behind both assets.
