I built CoinDrip: a free, Bitcoin DCA calculator — would love your feedback

Hey r/Bitcoin!

I built a simple DCA Calculator and I'm happy to make any improvements / tweaks based on feedback.

CoinDrip (coindrip.org).

What it does

• Pick weekly / bi-weekly / monthly buys
• Add an optional starting stack (defaults to 0)
• Tweak the annual growth assumption (includes some initial Growth Model's like Michael Saylor's etc)
• Auto-updates BTC stacked and Projected Future Portfolio value

How it’s built

• 100 % client-side (no log-ins, no cookies, no servers siphoning data)
• Vanilla HTML/JS + Chart.js (code needs a cleanup before I publish, but happy to share snippets or the whole repo if people care)

Why share?

1. Sanity-check the math — roast it if you spot errors.
2. UX nit-picks welcome (mobile quirks, wording, anything).
3. Feature wishlist? (e.g., auto-DCA reminders, historical back-test, dark mode?)
4. I hope this helps someone
