Track Stocks and Crypto in One Dashboard: A Complete Guide

7 min read

You've probably felt the friction: Your emergency fund is in a bank. Stocks are on a local broker's platform. US equities are through a different app. Crypto is scattered across three exchanges. Every time you ask yourself "How much am I actually worth?" — you need to log into five different places, copy down numbers, and do math in your head.

This isn't just inconvenient. When your portfolio spans multiple countries, currencies, and asset classes, fragmented data means you're flying blind.

The Cost of Fragmented Investments

A realistic portfolio for a globally diversified investor:

  • Bank account with emergency fund
  • Local stocks on a domestic broker (ETFs, individual stocks)
  • US stocks on a US broker (tech stocks, S&P 500 ETF)
  • Bitcoin and Ethereum on crypto exchanges
  • Maybe some international positions or foreign currency deposits

When every asset lives in a different system, you run into problems:

No unified view: You need to open 5–10 websites, log in to each, and manually note the balances. By the time you've done the math, prices have already moved.

Currency confusion: Domestic stocks in local currency, US equities in USD, crypto sometimes in USDT. Exchange rate swings change your real net worth daily, but you can't see it clearly.

Risk assessment becomes guesswork: You intended a 40/40/20 split across stocks, US equities, and crypto. But market moves may have shifted you to 30/50/20, and you won't notice without manually checking.

Rebalancing blind spots: Did one position grow too large? Are you underweight somewhere? Without a unified dashboard, these questions take real effort to answer.

Four Approaches Compared

Every solution involves trade-offs. Here's an honest look at four common approaches.

Option A: Manual Google Sheets

The DIY approach: build a spreadsheet, regularly look up prices and exchange rates, and manually fill in the data.

Pros:

  • Total control — data is entirely yours
  • Maximum flexibility in how you organize information
  • No third-party access needed
  • Free

Cons:

  • Requires regular manual updates across multiple platforms
  • Manually entered prices can be stale or incorrect
  • Hard to build professional visualizations from formulas alone
  • Currency conversion is tedious

This works well if your portfolio is simple (a few ETFs plus bank deposits) and you're comfortable with spreadsheets. For complex portfolios, the maintenance burden adds up.

Option B: Asset Aggregation Platforms (Morningstar, Yahoo Finance Portfolio)

These services let you add or link brokerage accounts and view everything in one interface.

Pros:

  • High automation — data pulls happen automatically
  • Professional analysis tools: charts, performance metrics, risk assessment
  • Single interface for everything
  • Some platforms offer excellent historical analysis

Cons:

  • Some features require account linking permissions
  • Connections can break and need re-authentication
  • Not all brokers and exchanges are supported
  • Crypto support is often less complete than stock tracking
  • Advanced analytics usually require paid subscriptions

Best for investors with complex portfolios who value convenience and are comfortable using third-party platforms. Major platforms typically have solid security practices, but if you prefer keeping financial data off external servers, other options may suit you better.

Option C: DIY API Automation

Developers sometimes write scripts connecting to broker APIs, crypto exchange APIs, and exchange rate APIs to automatically pull data into their own database or spreadsheet.

Pros:

  • Fully customizable — pull whatever data you want
  • Data stays on your own systems
  • Can achieve complete automation

Cons:

  • Requires programming skills
  • APIs change frequently, creating ongoing maintenance
  • Need to manage API keys and secrets securely

Great for technical users who enjoy building things. Not practical for most investors.

Option D: Google Sheets + WalletMap

WalletMap takes a middle-ground approach — using Google Sheets to keep your data under your control while automating the tedious price-update work.

Core idea: Your holdings live in your own Google Sheets. WalletMap connects to your Sheets, automatically updates stock prices, exchange rates, and crypto prices, then generates a visual dashboard.

How it works:

  1. Create a Google Sheets file listing all your holdings:

    • Cash: $100,000
    • TSMC (2330): 50 shares
    • Taiwan 50 (0050): 20 shares
    • Apple (AAPL): 10 shares
    • Bitcoin: 0.5 BTC
    • Ethereum: 5 ETH
  2. WalletMap connects to your Sheets (read-only access)

  3. WalletMap automatically:

    • Fetches latest stock prices
    • Gets real-time crypto prices
    • Converts exchange rates
    • Calculates total portfolio value
    • Generates charts: allocation pie, currency breakdown, performance trends
  4. Your dashboard shows:

    • Total net worth (auto-calculated)
    • Allocation breakdown by asset type and currency
    • Current prices and daily changes for each holding
    • Growth curves over time

Pros:

  • Data stays in your Google Drive — backend doesn't store sensitive information
  • Automatic price updates without manual lookups
  • Stocks, crypto, and multi-currency all supported
  • Free to use

Cons:

  • Holdings must be entered manually (no automatic bank sync)
  • Requires a Google account
  • You need to update Sheets when you buy or sell
  • Web-based, no native mobile app

Best for investors who want automated price updates but prefer not to store financial data on third-party servers. Much more convenient than pure manual Sheets, but not as fully automated as aggregation platforms.

In short: want maximum convenience → aggregation platforms. Want full customization → build it yourself. Want a balance between convenience and data control → Sheets + WalletMap. Simple portfolio and don't want to install anything → manual Sheets works fine.

A Real-World Example

Imagine this portfolio:

AssetHoldingCurrent Value
Cash (TWD)NT$100,000NT$100,000
TSMC (2330)50 sharesNT$240,000
Taiwan 50 (0050)20 sharesNT$48,000
Apple (AAPL)10 shares @ $180NT$58,500
Bitcoin (BTC)0.5NT$636,000
Ethereum (ETH)5NT$68,400
TOTALNT$1,150,900

The manual approach means logging into your bank, local broker, US broker, crypto exchange, and an exchange rate site, then converting and summing everything. That's 15–20 minutes of work.

With WalletMap, you list your holdings once in Sheets, and the dashboard shows auto-updated numbers. When you make trades, just update the Sheets.

Getting Started

  1. Create a Google Sheets file with all your holdings (cash, stocks, crypto)
  2. Connect WalletMap to your Sheets (read-only access)
  3. Let WalletMap handle price updates — stocks, crypto, and exchange rates refresh automatically
  4. View your complete picture on the dashboard — allocation charts, trends, currency breakdown

Conclusion

When your investments span multiple countries, currencies, and asset classes, a unified tracking tool saves real time and gives you much better visibility into your allocation.

Every approach has its advantages — aggregation platforms are the most hands-off, manual Sheets gives maximum flexibility, and WalletMap strikes a balance between convenience and data control. Choose whatever fits your habits best.

Regardless of which method you pick, the important thing is to start tracking. Seeing your complete asset picture clearly is the first step toward better investment decisions.
