  • Exit failure (Delta 7/10): you cannot get out at par, on time, or with what is yours.

  • Information failure: the number is wrong or bought, or your data leaks.

Review story
Why this provider can still be the right call
The short story
Api key blast radius — 8/10
Why it works
Users who want a simpler mainstream portfolio tracker for holdings visibility.
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 supported exchanges, wallets, integrations, and whether the reporting depth matches your actual monitoring needs before relying on it daily.
What changed
Still strongest where cleaner mainstream portfolio monitoring matters more than DeFi-native depth.
Choose something else if
Choose CoinStats if broader crypto-specific mixed coverage matters more than a simpler mainstream monitoring posture.
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
Api key blast radius — 8/10
Monitoring signal
Verified 18 August 2026 against the provider's own published sources; read again 29 September 2026.
Tradeoff signal
Tradeoff: The free tier is effectively a demo for this buyer: two total connections and ten tracked assets means anyone with a couple of exchanges plus a wallet pays $6.99/mo almost immediately — and while your API keys stay on your phone, your synced trades and balances sit on eToro-group servers under the broker parent's group privacy policy, which grants eToro broad rights to market to you and to share pseudonymised details with ad platforms.

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%).
