How to Track Your Crypto Portfolio for Free in 2026
A complete guide to tracking Bitcoin, Ethereum, and altcoin holdings without paying for a subscription or giving up your private keys.
Managing a cryptocurrency portfolio across multiple exchanges and wallets is notoriously difficult. Prices change every second, you're tracking dozens of coins across Binance, Coinbase, and cold storage, and most tracking tools either cost money or require connecting your exchange API keys.
This guide shows you how to track your entire crypto portfolio for free — without an account, without subscriptions, and without trusting a third party with your financial data.
The Problem With Most Crypto Trackers
Most popular crypto portfolio trackers like CoinTracker, CoinStats, and Delta have a common set of problems:
They require an account. Even for basic features, you must hand over your email address, creating a link between your identity and your crypto holdings.
They charge for real features. Free tiers are intentionally limited — historical data, tax reports, and multi-exchange syncing are locked behind $10–$30/month subscriptions.
They connect to your exchanges. Many trackers offer automatic sync by asking for your API keys. This introduces a security risk: if the tracker is breached, your keys could be exposed.
They only track crypto. If you also hold stocks, gold, or fiat savings, you need a separate app for each — making it impossible to see your complete financial picture.
A Better Approach: Manual Entry with Local Storage
The most private and secure way to track your portfolio is manual entry with local-first storage. You enter your trades by hand (buy price, quantity, date), and the app calculates your P&L, allocation, and performance using live prices — but stores all that data only in your browser.
This is exactly how WalletLens works.
Setting Up Your Portfolio in WalletLens
1. Open walletlens.live in any modern browser. No installation, no account.
2. Create a wallet on the Dashboard. Name it after your exchange or storage type — e.g. "Binance", "Ledger", "MetaMask".
3. Add your first trade. Tap the Buy button, search for your coin (Bitcoin, Ethereum, Solana, or any of 10,000+ assets), enter the quantity and price you paid, and the date.
4. Repeat for each holding. If you've been dollar-cost averaging into Bitcoin over two years, add each purchase separately for accurate average cost tracking.
5. Check your P&L. The Dashboard shows your total portfolio value (live), all-time P&L in dollars and percentage, and a breakdown by asset.
Reading the AI Analysis
Once you have at least two or three holdings, tap the AI tab on the Dashboard. WalletLens runs seven analyses entirely on your device:
- Health Score — a 0–100 rating of your portfolio's diversification and risk profile.
- Fear & Greed Gauge — composite sentiment from your portfolio's momentum, P&L ratio, and concentration.
- Stress Test — your portfolio value if the market drops 10%, 30%, or 60%, or rallies 50% or 200%.
- Entry Quality — whether you bought each asset above or below the current price.
- Rebalance Planner — what you'd need to buy or sell to reach equal-weight allocation.
Setting Price Targets
The Sell Targets tab lets you plan your exit strategy. For each asset, set up to five price targets with a quantity to sell at each level. WalletLens shows a progress bar against the live price so you know exactly how close each target is.
For example, if you hold 1 BTC and plan to sell:
- 0.2 BTC at $120,000
- 0.3 BTC at $150,000
- 0.5 BTC at $200,000
WalletLens tracks each tier separately and shows the projected proceeds in real time.
Backing Up Your Data
Since WalletLens stores data in your browser, clearing your browser storage would erase it. Use the Export feature on the Dashboard regularly. It generates a short WLZ code (a compressed text string) that you can save anywhere — a notes app, email draft, or password manager. To restore, paste the code into Import on any device.
Conclusion
Tracking your crypto portfolio doesn't require paying a monthly fee, handing over API keys, or creating an account. WalletLens gives you live prices, AI analysis, sell planning, and whale tracking in one free, private, browser-based tool. Your data stays on your device.
