## About

BitStack is a Bitcoin-focused portfolio tracker and financial planning platform. It helps Bitcoiners track holdings across self-custody wallets, Bitcoin ETFs, and stocks like MicroStrategy (MSTR). Features include AI-powered portfolio insights, Bitcoin-backed loan monitoring with liquidation alerts, risk management tools, and forecasting. Free calculators need no login. The app is for tracking holdings and loans you already have — BitStack is not a lender and does not originate loans.

## When to use the free calculator vs the app

- Use a free calculator for one-off math (liquidation price, LTV, margin call, down-payment comparison). No account required.
- Use the BitStack app to track live holdings, existing Bitcoin-backed loans, forecasts, and AI insights.
- Down-payment calculator: education only. No apply CTA. No lender directory.

## Core Features

- Multi-asset portfolio tracking (BTC self-custody, MSTR, Bitcoin ETFs, stocks)
- AI-powered portfolio advisor with personalized insights (powered by Gemini)
- Bitcoin-backed loan monitoring with liquidation price alerts
- Portfolio forecasting and growth projections
- Weekly portfolio email reports with market context
- Multi-user accounts with role-based access (owner/editor/viewer)
- Stripe-powered subscriptions with free and Pro tiers

HTTP JSON API (curl / WebFetch / non-Chrome agents): GET or POST /api/tools/down-payment — tools run_down_payment and compare_ltv_buckets (30/35/50% origination LTV). GET with no params returns schemas. Well-known MCP/agent discovery (no llms.txt required): /.well-known/mcp.json — points at that API and names both tools. The 50% dump is a scenario, not a forecast. Education only.

Canonical formulas (definitional unless a source is listed) are in llms-full.txt and each markdown endpoint.
