The short story
A strong fit when the tracker needs to stay wallet-first and onchain-native while offering richer portfolio context than a simpler holdings view.

Review story
Why this provider can still be the right call
When to step back
Users who mainly want broad exchange syncing or the softest mainstream monitoring experience.
Before you act
The few things worth checking before you trust this as your answer
Before you act
Verify supported wallets, chain coverage, reporting views, and whether the tracker matches your actual account mix before relying on it daily.
What changed
Still strongest where wallet-first tracking and richer onchain context matter more than broader exchange-heavy coverage.
Choose something else if
Choose CoinStats if broader wallet-and-exchange coverage matters more than wallet-first onchain insight.
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.

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%).
