The truth about trading with leverage

Who is James Wynn?

Before his headline-making trades, James Wynn was already experimenting with high-leverage strategies on memecoins, an approach that later pushed him into the spotlight.

James Wynn is a pseudonymous crypto trader who came to prominence in 2022-2023 via memecoins. One of his earliest public breakout moves was turning a modest investment into a multimillion-dollar return via Pepe (PEPE) when its market capitalization was tiny.

That PEPE trade established several hallmarks of his style: high leverage, aggressive risk-taking and a strong “narrative” component with calls on social media and predictions.

In early 2025, Wynn moved heavily into perpetual futures on decentralized derivatives platforms, most notably Hyperliquid. These are instruments that allow a trader to open a position with borrowed capital, magnify gains (and losses) and hold indefinitely, subject to funding rates, without expiration. Wynn began running positions with leverage of up to 40x on billion-dollar notional sizes.

This transition made him a so-called “main character” in crypto-trading lore: His positions were large, transparent and risky. He became a symbol of what was possible when combining capital, leverage, social visibility and conviction — but also of what could go very wrong.

James Wynn’s early PEPE trade and initial profits

By early 2025, Wynn was already gaining attention in trading circles after he turned bold bets on Hyperliquid into positions showing tens of millions in unrealized profit.

Wynn had significant successes before his more dramatic losses. Inspired by the well-known internet meme, he invested around $7,000 in the PEPE memecoin in 2023, when its market valuation was reportedly under $600,000. The token went viral, helped in part by Wynn’s early entry and promotion through various channels.

By mid-2025, PEPE’s market capitalization had climbed to around $10 billion. This matched Wynn’s early forecast of a $4.2 billion market cap, made when the token was reportedly valued near $4.2 million. His original investment turned into an estimated $25-million profit due to this growth.

Building on this success, Wynn added high-leverage positions on decentralized platforms such as Hyperliquid to his trading practices. He used aggressive leverage trades to build a $3-million stake into $100 million in a matter of months. He opened a long Bitcoin position in May 2025, holding 5,520 Bitcoin (BTC) at 40x leverage, which, at its peak, displayed unrealized gains of around $39 million.

Wynn also realized profits along the way: He closed portions of positions while still in the green, capturing gains in PEPE and other swing trades. His early success wasn’t just on paper; at times, he turned his bold calls into real profits. Within the cryptocurrency community, his moves and his approach were both praised and criticized for quick execution and high risk-taking.

James Wynn’s losses and what went wrong

Wynn’s fortunes flipped overnight when Bitcoin fell below $105,000, triggering liquidations that erased nearly $100 million from his leveraged long.

The most dramatic collapse came in late May 2025, when Wynn’s large 40x BTC long on Hyperliquid (notional above $1.25 billion) unraveled. Bitcoin’s drop below $105,000 triggered cascading liquidations. Reported losses in that period approached $100 million, turning prior paper gains into sharp drawdowns.

Wynn didn’t just suffer total closures; partial liquidations also played a role. High volatility meant that even before full liquidation, parts of his positions were auto-closed to protect margin, chipping away at buffer capital. On June 3, Wynn risked nearly $100 million on a second leveraged Bitcoin bet, publicly sharing his liquidation level and drawing both community support and criticism. On June 5, 2025, he was partially liquidated three times in an hour, for a total of about 379 BTC, roughly $39 million at the time.

In addition, Wynn’s exposure to memecoins and higher volatility assets meant that price swings could be swift. Even when core assets like Bitcoin were relatively stable, the leveraged positions magnified small moves.

In August 2025, James Wynn suffered a $22,627 loss on a 10x leveraged Dogecoin position, attributing the liquidation to coordinated actions by a memecoin “cabal” and signaling his intent to “go max long” as he anticipated the end of the market downturn.

Did you know: Emotional trading and piling on more leverage made things worse for Wynn. Instead of taking risk off after making gains, he often added to trades or switched sides at high leverage. Market moves that might have been manageable with smaller bets turned into wipeouts.

Lessons to learn from James Wynn’s case

Wynn’s rise and fall show that in crypto, leverage isn’t just about multiplying gains; it’s about how quickly missteps compound into irreversible losses.

For anyone interested in crypto trading, Wynn’s saga offers a number of cautionary lessons.

Leverage is a double-edged sword

High leverage — 20x, 40x or more — offers huge profit potential but demands near-perfect timing and risk control. Because crypto is so volatile, even small ticks against you become large losses. Wynn’s experience underlines this: Gains of tens of millions, but losses of nearly the same magnitude, and sometimes more.

Partial liquidation risk and capital erosion

Even without a full wipeout, repeated partial liquidations during volatile swings cut into margin, shrink positions and drain the account. Risk management has to consider not just the worst case but the drag of back-to-back losses. For Wynn, partial liquidations often chipped away at his trades before the final collapse.

The importance of an exit strategy and profit-taking

Though he frequently held onto positions for too long or extended them excessively, Wynn did book profits in certain transactions even during his winning runs. A controlled withdrawal can stop the losing cycle, even if it means giving up some possible gains.

Platform and technical risks

Platforms like Hyperliquid offer high leverage, transparency and speed but also carry risks: slippage, funding costs, liquidations, margin calls and even external pressure. The larger your position relative to the platform liquidity, the more you may be “in focus” and possibly more exposed to adverse moves.
