      <title>I fact-checked 5 viral "my AI bot made money" posts against primary data. None survived.</title>

      <description>&lt;p&gt;Over the past week my feed filled up with posts of the same shape: someone hands an AI agent fifty-odd dollars, walks away, and comes back to thousands. I run a small, boring, fully logged trading system myself, so I checked five of these claims against primary sources: on-chain pool data, official fee schedules, the projects' own sites and the authors' own public demos.&lt;/p&gt;

&lt;p&gt;I used the same five questions every time:&lt;/p&gt;

&lt;ol&gt;
&lt;li&gt;Is there verifiable evidence, such as a public wallet or trade history?&lt;/li&gt;
&lt;li&gt;What does the author gain if you copy them?&lt;/li&gt;
&lt;li&gt;Do the post's own rules and fees allow its own first trade?&lt;/li&gt;
&lt;li&gt;What daily return does the start and end balance imply, and for how many days in a row?&lt;/li&gt;
&lt;li&gt;Can the reader even execute it from where they live?&lt;/li&gt;
&lt;/ol&gt;

&lt;h2&gt;
  
  
  1. "Mint a yen stablecoin at 1 yen, sell it on a DEX for 3 yen, repeat"
&lt;/h2&gt;

&lt;p&gt;I pulled the live pools. The premium was real: several Uniswap pools priced the coin at 1.7 to 2.1 yen, up about 70% in 24 hours, then down about 20% within the next hour.&lt;/p&gt;

&lt;p&gt;The mechanism is legitimate. Issue at par, sell where it trades rich. That is how the peg is supposed to be enforced.&lt;/p&gt;

&lt;p&gt;"Repeat" is the part that fails. Every sale pushes the pool price back toward par, so total extractable profit is capped by the USDC sitting in the pool, a few tens of thousands of dollars each. Issuance needs a bank transfer and has a per-issuance limit, so people already holding inventory, and bots, take it first. The hourly decay I measured is exactly that happening.&lt;/p&gt;

&lt;h2&gt;
  
  
  2. "My bot launches tokens and skims 0.5% of every trade. $52 became $3,292 in 18 hours"
&lt;/h2&gt;

&lt;ul&gt;
&lt;li&gt;The 0.5% in the post is the trading app's own fee. It goes to the app, not to the token creator. The creator fee on the launchpad's bonding curve is 0.30% according to its public fee page.&lt;/li&gt;
&lt;li&gt;To collect $3,240 at 0.30% you need about $1.08M of volume, roughly $180k per token across six tokens. That is graduation-level activity, and graduation rates on that launchpad run between 0.2% and 1.4%.&lt;/li&gt;
&lt;li&gt;About 28,000 tokens launch per day, while only 4,000 to 7,000 wallets claim creator fees on a given day, and the top 25 creators took over $745k. Most launches earn nothing.&lt;/li&gt;
&lt;li&gt;The launchpad's own co-founder said publicly that creator fees "may have skewed the incentive for users to engage in low-risk activity (coin creation)" and overhauled the scheme in January 2026.&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;There is a small real effect: sniper bots buy every new launch, so a creator can earn a few dollars with zero organic buyers. A few dollars, not thousands. And the money comes from buyers who, per a study of 200,000+ tokens, profit in fewer than 0.5% of cases once the first 10% of supply is gone.&lt;/p&gt;

&lt;h2&gt;
  
  
  3. "Autonomous trader: $50 to $420 in five hours" (then it went negative)
&lt;/h2&gt;

&lt;p&gt;The project's own site says "No trades executed". No wallet address, no performance numbers. Unverifiable.&lt;/p&gt;

&lt;p&gt;The author's lesson, though, is correct and matches the statistics: finding entries means nothing without exits and risk limits.&lt;/p&gt;

&lt;h2&gt;
  
  
  4. "A chief of staff and six seated bots took $89 to $7,769"
&lt;/h2&gt;

&lt;p&gt;This one came with paste-ready prompts, which made it easy to check against itself.&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;The post links a trading app referral twice. That app's referral programme pays the referrer up to 25% of referees' trading fees, in near real time. A high-turnover multi-bot setup is the most profitable thing the author could possibly recommend, win or lose.&lt;/li&gt;
&lt;li&gt;The post's own execution rule says a $20 entry against a $0.95 minimum fee is 4.75% and must not be filled. But with an $89 bank and the post's own 6% position cap, the largest ticket is $5.34, which is 17.8% per side. By its own rules the desk could never have placed its first trade.&lt;/li&gt;
&lt;li&gt;It says every fill goes through that one app, yet the claimed profit came from prediction markets, which that app does not offer as far as I could find.&lt;/li&gt;
&lt;li&gt;The +22% day: 18 books at an average 3.61% of bank is about $4,137 deployed. Making $1,403 on that means +34% per book on average including four losers, with a stated average hold of 22 minutes.&lt;/li&gt;
&lt;/ul&gt;

&lt;h2&gt;
  
  
  5. An open-source bot that lets an AI model make a market-making decision every 300 ms
&lt;/h2&gt;

&lt;p&gt;This author is honest: no performance claims, no referral links, MIT licence. So I looked at the public demo he links.&lt;/p&gt;

&lt;p&gt;Dry-run mode, the real model, 143,535 fills: realised PnL of about minus $144, which the dashboard shows as minus 299% of its reference capital. Gas is booked at zero in dry-run, so live would be worse. The first issue on the repo is titled "It's losing money".&lt;/p&gt;

&lt;p&gt;This is adverse selection. A retail market maker gets filled precisely when someone better informed wants the other side. Deciding in 300 ms does not change who is on the other side.&lt;/p&gt;

&lt;h2&gt;
  
  
  The four-point check
&lt;/h2&gt;

&lt;p&gt;You can run this on any such post in a few minutes:&lt;/p&gt;

&lt;ol&gt;
&lt;li&gt;Is there a public wallet or a trade history link?&lt;/li&gt;
&lt;li&gt;Is there a referral link or a paid group?&lt;/li&gt;
&lt;li&gt;With the fees stated in the post, can the starting balance place even one trade?&lt;/li&gt;
&lt;li&gt;Does the start-to-end balance imply a daily return that must repeat for days?&lt;/li&gt;
&lt;/ol&gt;

&lt;p&gt;All three profit-claim posts fail on points 1 and 2 alone.&lt;/p&gt;

&lt;h2&gt;
  
  
  What I actually run instead
&lt;/h2&gt;

&lt;p&gt;A deliberately dull system: daily-bar trend following on spot crypto at a Japanese exchange, post-only limit orders, no leverage, 1% risk per trade, a hard 30% drawdown stop. My own backtest over 2018 to 2026 shows roughly the same return as volatility-targeted buy-and-hold with about half the drawdown, and flat-to-negative results in ranging years. Walk-forward out-of-sample Sharpe is 0.85. It has made zero trades in its first week because no breakout has occurred, and I count that as working.&lt;/p&gt;

&lt;p&gt;It also broke once already. The PC clock drifted 16 seconds ahead of the exchange, signature validation failed, my fallback code computed equity from a paper balance and falsely tripped the kill switch. No orders were sent. I fixed it by syncing the signing timestamp to the server clock and by aborting without touching state when validation fails. Operational holes scare me more than strategy losses.&lt;/p&gt;

&lt;p&gt;The code, the full verification numbers including the bad years, and the hourly sensor logger are here if you want to read or run them:&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;Engine B/C Kit (backtest, walk-forward, live engine): &lt;a href="https://wataflow1.gumroad.com/l/engine-bc-kit" rel="noopener noreferrer"&gt;https://wataflow1.gumroad.com/l/engine-bc-kit&lt;/a&gt;
&lt;/li&gt;
&lt;li&gt;Crypto Market Sensor Kit (funding, attention, LLM-scored headlines, plus a script that tests whether the flags mattered): &lt;a href="https://wataflow1.gumroad.com/l/sensor-kit" rel="noopener noreferrer"&gt;https://wataflow1.gumroad.com/l/sensor-kit&lt;/a&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;Not investment advice. If a post cannot show you a wallet, assume the screenshot is the product.&lt;/p&gt;
