TradeGPT pitch deck: sign up customers, offering free LLM credits to support trades. Ask them what their risk/return preferences are. Use their funds to buy inexpensive market trackers. Randomly propose shuffles of market portfolio around between their accounts: no actual trades, to save the TCs. If they sell out of a rise, cheap LLM tells take profit story; when out of a fall, a stop loss story. Give them the vol they want, stories galore, cheap GPT calls, and 1% less than the market return.
