Bitcoin’s wild ride on Polymarket: From $20 to $121,000 thanks to a bot

From $25 to $121,000 in a month on Polymarket: The insane story of @xuanxuan008

Cryptocurrencies, including Bitcoin, have a reputation for being highly volatile. In other words, the price moves and sometimes very quickly. With the Up & down 5 minutes market on Polymarket, you bet whatever amount you want on the direction of Bitcoin over the next 5 minutes.

The advantage is that there is no leverage involved unlike in traditional trading. For example, in just one month, with over 9,360 trades, @xuanxuan008 pocketed more than $121,000 on these “up” or “down” bets. 

This bot/trader became a legend in just a few weeks. His biggest win on a single trade is only around $593. This means he strings together small wins (usually between $25 and $100), which ultimately leads to this incredible result.

It is these small repeated predictions that end up drawing an almost perfect profit curve. Even with a win rate of around 48%, the losses go unnoticed in an ocean of gains. He is currently at the very top of the Polymarket leaderboard, and naturally people are wondering: how does he do it? 

The bot trend on Bitcoin up and down: Does it work?

Yes, and it works incredibly well. For months, the “Bitcoin Up or Down” markets in 5 minutes (and sometimes 15) have become the favorite playground for bots. Why? Because there are persistent inefficiencies and the price on Polymarket sometimes lags behind the spot price on Binance or Coinbase. People bet on instinct, and the YES/NO prices do not always reflect the true probability in real time. Bots exploit this down to the millisecond.

Here are the most famous bots on the market:

-> Gabagool22: the legendary one. Started from $1,200 and ended up with $868,000 thanks to pure arbitrage (buying both sides when the total is under $1).

-> Sharky6999: the most consistent, with $852,000 in profit and a 95% win rate.

-> Anonymous “Claude bots” running 200 to 400 trades a day and generating hundreds of thousands of dollars.

The most successful strategies are arbitrage (zero risk), taking advantage of price discrepancies, following the momentum (tracking live spot movements) or using AI bots that learn on their own. The result: tens of millions of dollars in collective profits on these markets in 2025-2026. However, all of this only works as long as the inefficiency exists. Indeed, Polymarket is evolving: fees are changing and competition is intensifying. But for now, it is a real cash machine for those with the right setup. So how do you do it? Is it possible to create your own bot? Yes, even though it is a real battle against the biggest players. But it is more accessible than you might think, especially thanks to open source tools. 

The tutorial that went viral on X comes from @0xMovez. He explains how to launch a Hermes Agent with one click (an autonomous AI agent by NousResearch) to trade these UP/DOWN markets. In short, Hermes is not just a simple script: it has memory, learns from its trades, can break down tasks and adapts on its own. Movez provides the step by step guide, here it is:
