Review story
Why this provider can still be the right call
Why it works
Users who want broader mixed coverage across wallets and exchanges in one tracker.
When to step back
Compare the full pool — the measurable record differs more than the marketing does.
Before you act
The few things worth checking before you trust this as your answer
Before you act
Verify the exact exchanges, wallets, and chains you need, plus reporting and alerting expectations, before making it your main tracker.
What changed
Still strongest where broader mixed account coverage matters more than the cleanest onchain-native tracker experience.
Choose something else if
Choose Zerion if you want a cleaner wallet-first onchain experience, or Delta if a more mainstream holdings tracker is enough.
Portfolio trackers are reviewed on whether someone could trade or withdraw with a leaked API key and whether that has already happened (30%), who pays for the free dashboard and what of yours they are buying (25%), whether you will ever find out which one is wrong when the app and your exchange disagree on a balance (25%), and what the free tier quietly stops tracking and whether the app will outlive your history (20%). API-key blast radius leads because it measures what the vendor can technically do with the credentials you hand over: whether read-only is only instructed or enforced at connect time, where the keys live, and every dated incident with its disclosure.
Coverage signal
Sync fidelity and gap honesty — 8/10
Monitoring signal
Verified 18 August 2026 against the provider's own published sources; read again 29 September 2026.
Tradeoff signal
Tradeoff: The tracker and a hosted hot wallet with buy/swap/stake live in one product: the June 2024 breach drained 1,590 CoinStats Wallets (~$2.2M) even though exchange connections survived, read-only is instructed rather than provably enforced (the Binance guide gives no permission instruction at all), and the Kraken guide tells you to set API-key 2FA to 'No method'.

What is the best crypto portfolio tracker for most users?
The best tracker is usually the one that covers your actual wallets and exchanges reliably and makes balances and performance easier to understand without creating more setup friction.
Do I need a portfolio tracker if I only use one exchange?
Not always. Portfolio tracking becomes much more useful once you use multiple wallets, exchanges, or onchain positions that are hard to monitor in one place.
What matters most when choosing a crypto tracker?
The ranking weighs what someone could do with your API keys if they leaked, and whether that has happened (30%), who pays for a free dashboard and what of yours they buy (25%), whether the app tells you when its balance and your exchange's disagree (25%), and what the free tier quietly stops tracking and whether the app will outlive your history (20%).
