## About

BTC DCA Engine answers one question with arithmetic instead of opinion: what would a regular buying plan have been worth?

Give it an asset, an amount and a schedule — daily, weekly, monthly or quarterly — and a start date, and it returns what you put in, what it would be worth at the last close, the profit, the simple and money-weighted returns, the units held, and end-of-year checkpoints along the way. It can compare plans side by side and rank them, and it can return the individual purchases behind any figure.

Every answer carries a link that reopens the same run in the web app, pinned to the exact data it was computed from, so a number in a conversation can be checked rather than taken on faith. Prices come from published daily closes; inflation and rate series come from the St. Louis Fed. There is no forecasting, no advice, and no trading — it reads history and does the sums.

Free with no account: seven assets including Bitcoin, Ethereum, Solana, XRP, the S&P 500, the Nasdaq 100 and gold, and two plans per comparison. A BTC DCA Engine account covers the rest of the catalogue, larger comparisons, and the risk, inflation, lump-sum and rules-based overlays.

## How to use

1. **Add it in ChatGPT** Open BTC DCA Engine in ChatGPT's Plugin directory (button above), select + to add it and sign in if asked.

2. **Use it in a chat** Type @ in the composer and pick BTC DCA Engine, or start your message with its name. ChatGPT may also suggest it when it fits what you ask.

## Skills

- **dca-simulations**: Use when someone asks what a regular buying plan would have been worth — "what if I'd put $50 a week into Bitcoin since 2018" — or wants to compare assets, buying schedules or start dates against real price history. Covers how to call the BTC DCA Engine tools and how to report what comes back.

## Example prompts

- "What would $50 a week into Bitcoin since January 2018 be worth today?"
- "Compare $100 a month into Bitcoin and the S&P 500 since 2020."
- "Which assets can you simulate, and how far back does each one go?"
