Crypto Million: rich in 15 minutes thanks to a flaw in XRPWhat if 15 minutes were enough to win big with XRP on Binance, in the face of losing bots? A bold trader did it, and the profits were there!A jackpot in 15 minutes on XRPOn Polymarket, a trader known by the pseudonym a4385 turned a simple 15-minute window on XRP into a gain of about $233,000 in one night, capitalizing on extremely low liquidity and sparse order books on Binance. On January 17, he targeted the market titled 'Will XRP drop or rise' for that day and methodically bought nearly 77,000 call contracts at an average price of $0.48, while most of the opposing flow came from market-making bots programmed to react to price discrepancies.For a good part of this short session, XRP was actually slightly down, leading one to think that these contracts would end up worthless. Two minutes before expiration, a spot purchase of about $1 million in XRP on Binance, however, caused the price to rise by about 0.5%, which was enough to push all its contracts into the green and trigger a massive cashing out of the winning position.This spectacular operation relies less on a long-term vision of XRP than on a fine reading of market conditions: reduced volume, a thin order book, and mostly automated counterparties. By gradually pushing the price of bullish shares up to about $0.70, a4385 attracted the bots that, thinking they were selling high on an overestimated probability, ceded him even more contracts in an environment where almost no one was there to rebalance the market.The total costs of the operation, including fees and slippage, are estimated at just over $6,000, largely covered by the final profit, proving that a well-managed cost structure can make a strategy highly concentrated on a few minutes viable. Strengthened by this success, the trader replicated the maneuver on other 15-minute windows overnight, notably on Bitcoin, at the expense of certain bots like Aleksandmoney, which saw nearly $34,000 evaporate, representing all of its annual gains.This logic of exploiting flaws is not limited to XRP. Another trader, hai15617, recently made waves on Polymarket by raking in around $100,000 in profit on the same day he registered, January 14, before surpassing $235,000 the very next day. In just ten predictions, including one position on Bitcoin that alone earned him nearly $99,800, he displayed a return of 887%, demonstrating that a few well-calibrated bets can erase multiple losses.Once again, the core of the strategy was not to guess the future trend of the crypto market, but to spot temporary price errors in very short markets where the displayed probabilities no longer reflected the actual risk. By betting, for example, $11,000 on a decline of Bitcoin deemed very unlikely by the market, hai15617 illustrated how prediction markets can become explosive playgrounds, where the mechanics of odds and microstructure matter as much as the direction of the chart.The moral of the story: fortune favors the swift, especially when the bots are dragging their feet.
