How to Track Your Crypto Portfolio (and Stay Ready for Tax)
Once your crypto is spread across a couple of exchanges and a wallet or two, keeping track of what you actually own โ and what you paid for it โ gets messy fast. A portfolio tracker fixes that, and it quietly does half your tax homework at the same time. Here is how to use one properly.
Key takeaways
- A tracker shows all your holdings across exchanges and wallets in one place.
- It records your cost base, which makes tax time far easier.
- Connect it with read-only API keys or public addresses โ never private keys.
Why bother tracking?
Two reasons. First, clarity: instead of logging into five apps, you see your whole portfolio, its value and its performance at a glance. Second, and less obvious โ tax readiness. In most countries every sale, swap or spend is a taxable event, and you need to know your cost base (what you originally paid). A tracker records this automatically as you go, so you are not reconstructing a year of trades in a panic at tax time.
How trackers work
You connect the tracker to your accounts in one of two safe ways:
- Read-only API keys. Exchanges let you create keys with view-only permission โ the tracker can see your balances and history but can never move funds.
- Public wallet addresses. For on-chain wallets, you paste your public address (safe to share); the tracker reads the blockchain to see your holdings.
From there it pulls everything together, values it in your local currency, and keeps a running history.
The one security rule
Never give a tracker anything that can move your money. That means: no private keys, no recovery phrase, and no API key with withdrawal or trade permissions enabled. A legitimate tracker only ever needs read access. If a tool asks for more, walk away โ and read our guide to spotting scams.
Trackers vs tax tools
There is overlap. Pure trackers (like CoinStats or Delta) focus on showing your portfolio and often have generous free tiers. Tax tools (like Koinly and CoinLedger) do the tracking and generate compliant tax reports, applying your country's rules. If you only want to watch your holdings, a free tracker is perfect; if you also need to file, a tax tool earns its keep.

Frequently asked questions
Are crypto portfolio trackers safe?
They can be, if you connect them the right way. Always use read-only API keys (which can view balances but never withdraw) or public wallet addresses. Never give a tracker your private keys, your recovery phrase, or an API key with withdrawal permissions.
What is the best free crypto portfolio tracker?
Several good trackers have free tiers โ CoinStats and Delta are popular choices for viewing all your holdings in one place. If your main goal is tax, a dedicated tool like Koinly does tracking plus compliant reports.
