🧠 The Why (Problem)

Crypto investing is already volatile. The last thing I need is a dashboard that gives me vibes instead of insights.

When I tried tracking my crypto investments across platforms—Coinbase, Binance, random cold wallets, Excel sheets—I was met with:

  • Missing data,
  • No idea of true profit/loss, and
  • A pile of trades that made it feel like I was playing 3D chess blindfolded.

All I wanted was:

  • What I bought
  • When I bought it
  • For how much
  • And what it's worth today

So… I built the dashboard I couldn't find anywhere.

⸻

✨ What I Built

This dashboard is like a crypto accountant, but without the judgment.

  • 📂 Upload your crypto trades (.csv, .xlsx)—from any exchange
  • 🧮 Instantly get net holdings, average cost, and current value
  • 📈 Live price updates from CoinGecko, Binance, Coinbase (with fallback logic)
  • 🔄 Manual price overrides if APIs misbehave
  • 💸 Auto-calculated P&L and CAGR
  • 🧾 Add/edit individual trades manually
  • 📊 Beautiful summary cards, bar charts, and a pie chart of allocation
  • 🌗 Dark mode to match your existential market moods

😬 The Struggles I Faced (aka: Why Crypto Bro Tools Didn't Work for Me)

You'd think building a dashboard was just a few tables and charts. You'd be wrong.

⚠️ 1. Live Price Hellscape

Unlike stocks, there's no single source of truth for crypto prices. I had to:

  • Scrape CoinGecko (80% reliable)
  • Fallback to Binance and Coinbase APIs (which rate-limit and occasionally ghost you)
  • Convert everything into CAD

Solution: I wrote a failover chain. CoinGecko → Binance → Coinbase. Still failing? Prompt the user to enter the price manually like a rebel.

⸻

💱 2. Forex: Again. Because Crypto.

Even if I bought in USDT or BTC, I wanted to see my total value in CAD. That meant:

  • Handling conversion at the right time (not today's rate)
  • Keeping things consistent for CAGR and P&L

Solution:

  • CAD conversion logic baked in
  • Manual override for control freaks (like me)

⸻

🧮 3. Transaction Chaos

Some trades came in .csv, others in .xlsx. Some had columns like PAIR, others used SYMBOL.

Solution:

  • Flexible parsing logic using SheetJS
  • Smart recognition of symbol, amount, side (BUY/SELL), value, price, and fees
  • Error messages with sass if the file was broken

⸻

🧾 4. Manual Holdings Control

Sometimes I wanted to override the calculated holdings (especially for assets not actively traded or moved to cold storage).

Solution:

  • Manual Holdings tab with input fields
  • Updates real-time performance KPIs and charts

⸻

📊 5. Making It Look… Not Like a Spreadsheet

Crypto data is messy. I wanted to visualize it:

  • Pie chart for allocation
  • Bar charts for returns and market value
  • Clean tables with alt-row colors and hover states

Solution:

  • Used Chart.js with a bright color palette
  • Built light/dark themes
  • Designed it to be responsive on mobile/tablet (trading insights on the go!)

⸻

😎 What Makes This Different

There are tools out there—but they're:

  • Too technical (for devs only)
  • Too clunky (hello, 2007 UI)
  • Too centralized (do I really want to sync my wallets with your cloud?)

This dashboard:

  • Runs locally
  • Works offline
  • Gives instant insights
  • Is fully customizable
  • Doesn't store your data (privacy FTW)

👨‍💻 For the Developers

  • Frontend: HTML, CSS (Custom), JavaScript (no frameworks)
  • Libraries: Chart.js, SheetJS

Features:

  • Multi-API price fetching with failover logic
  • Flexible CSV/XLSX parsing for various exchange formats
  • Real-time CAD conversion with manual override
  • Local storage for manual entries and preferences
