Why track your crypto portfolio
Most crypto holders underestimate how much their overall exposure drifts over time. A portfolio that started as 60 percent Bitcoin and 40 percent Ethereum a year ago might now be 75 percent Bitcoin and 25 percent Ethereum if BTC outperformed, or vice versa. Without a simple overview, these drifts compound over cycles and produce a risk profile very different from what the investor originally intended.
Tracking also matters for tax planning. Capital gains and losses accumulate across many small events, and a once-per-year glance at realized outcomes is much less useful than a running total. Portfolio tracking is the first step toward making intelligent decisions about when to take profit, when to rebalance, and when to realize losses for tax optimization.
Finally, tracking is a behavior amplifier. Investors who regularly see their positions in dollar terms, not just coin quantities, tend to make better decisions. A position that has grown to 40 percent of net worth looks very different in absolute dollars than as a coin balance. Seeing the number helps enforce discipline around position sizing and prevent accidental concentration.
How our portfolio tracker works
Add a holding by picking a coin from the top 100 list (or typing any ticker symbol that CryptoCompare supports), entering the amount you own, and optionally the buy price you paid. Click Add, and the holding appears in the table below with its current price, current value, 24 hour change, and estimated profit or loss if you provided a buy price.
The portfolio summary at the top shows your total value in US dollars, the 24 hour change in both dollars and percent, your all-time profit or loss based on the buy prices you entered, and the count of distinct positions you hold. The pie chart below the table shows your allocation by current market value, which is usually more useful for rebalancing decisions than looking at coin quantities.
Prices refresh every 60 seconds from CryptoCompare, which aggregates data across hundreds of exchanges. The refresh is automatic, so as long as the tab is open, your portfolio values stay reasonably current. Export to CSV at any time to back up or analyze elsewhere. Click Clear all (and confirm the prompt) to wipe your portfolio and start fresh.
Privacy and security
The tracker is built on a strict privacy-first principle. Your portfolio data is stored exclusively in your browser localStorage, a mechanism built into every modern browser for site-local data storage. It never leaves your device. Our server does not see your holdings, your amounts, your buy prices, or anything else. You do not create an account. You do not provide an email address.
The only network traffic is the request to CryptoCompare to fetch live prices, and that request only contains ticker symbols (for example “BTC,ETH,SOL”), never your quantities. CryptoCompare cannot derive your portfolio from those requests because the same symbols would be requested by anyone converting BTC to USD on this page. The fingerprint is not unique to you.
This design has trade-offs. Because your data lives only in your browser, clearing your browser cache or cookies erases your portfolio. Switching devices or browsers means starting over (or importing from a CSV you exported earlier). There is no “sign in on another device” feature because there is no account system to sign in to. For most users, this trade is worth it. For those who want sync across devices, a dedicated service like CoinTracker or Rotki is a better match, at the cost of sharing your data with that provider.
Features and limitations
What this tracker does well:
- Zero friction. No signup. No account. No email. Open the page and start adding positions.
- Privacy first. Data never leaves your browser. No analytics on your specific portfolio.
- Live pricing. Prices refresh every 60 seconds from a reputable aggregator.
- Clean overview. Total value, 24 hour change, all-time profit or loss, allocation chart in one view.
- Export any time. CSV export for backup, spreadsheet analysis, or import into other tools.
What it does not do, by design:
- No automatic exchange import. API connections to exchanges require a signup and break the privacy model.
- No cross device sync. Data is local to each browser on each device.
- No per-trade history. This is a current holdings tracker, not a trade log. For trade-level detail, use our profit and loss calculator.
- No tax reports. See our tax calculator for gain estimates.
- No DeFi positions. Staked balances, LP positions, and DeFi yield are not tracked automatically. Enter them manually if you want rough visibility.
Portfolio diversification tips
A few rules of thumb that experienced crypto investors often follow. None are absolute, but all are worth considering when deciding how much of each asset to hold.
- Anchor in Bitcoin. Most long-horizon investors keep 40 to 70 percent of their crypto exposure in Bitcoin. It has the longest track record, the deepest liquidity, and the most mature institutional support. Deviating from this anchor should be a deliberate decision, not an accident of drift.
- Limit single altcoin exposure. Individual altcoins carry protocol-specific risk that Bitcoin does not. A common rule is to keep single alt positions under 10 to 15 percent of the portfolio, so that a catastrophic failure of any one coin is survivable.
- Segment by time horizon. Long-term holdings (the core Bitcoin and Ethereum allocation) should be separated mentally and ideally operationally from short-term trading positions. The behaviors that work for each are different.
- Keep stablecoin dry powder. Some allocation to stablecoins (USDC, USDT, or similar) preserves optionality during drawdowns. The exact amount is personal, but zero stablecoin reserves means you cannot take advantage of major dislocations.
- Total portfolio context. Crypto is one of several asset classes you own. For most investors, total crypto exposure as a percentage of overall net worth should remain modest (often under 10 or 20 percent). The portfolio chart above only tracks the crypto portion.
When to rebalance
Rebalancing is the process of bringing your portfolio back toward its target allocation by selling what has grown and buying what has lagged. It is counterintuitive because it feels like punishing winners, but academic research consistently finds that systematic rebalancing improves risk-adjusted returns over long horizons.
Practical rebalancing rules for crypto:
- Threshold-based. Rebalance when any position drifts more than 20 percent (relative, not absolute) from its target. For example, a 50 percent BTC target becomes a trigger when BTC exceeds 60 percent or falls under 40 percent.
- Calendar-based. Review and rebalance quarterly or semi-annually regardless of drift. Simpler but can miss meaningful moves between review dates.
- Partial rebalance. Instead of restoring full targets, trim half the excess. This preserves some of the momentum while preventing runaway concentration.
- Rebalance into weakness. When new capital comes in (from income or other sources), direct it toward the underweight positions rather than the winners. This rebalances without triggering taxable sales of appreciated positions.
Tax considerations matter for rebalancing. In the US, selling an appreciated long-term holding creates a taxable gain, so the after-tax math of rebalancing may be worse than the pre-tax math suggests. Rebalancing in tax-advantaged accounts (where available) or using tax loss harvesting to offset gains reduces this drag. See our tax calculator for rough estimates before triggering large rebalance sales.

Frequently asked questions
Do I need to sign up?
No. The portfolio tracker requires zero signup, zero account, zero email. Everything is stored in your browser localStorage. If you clear your browser data, your portfolio is gone, so export a CSV periodically if you want a backup.
Where is my portfolio data stored?
Exclusively in your browser using the localStorage API. It never leaves your device. No server sees it. The only network traffic from this page is fetching live prices from CryptoCompare, which sends only the coin symbols (not your amounts or your portfolio structure) in the URL.
Can I use this on mobile?
Yes. The tracker works on phones and tablets. However, localStorage is tied to the specific browser on the specific device. You cannot share a portfolio across devices without manually re-entering the data or transferring an exported CSV.
How often do prices update?
Prices refresh automatically every 60 seconds while the page is open. The live data comes from CryptoCompare, which aggregates across hundreds of exchanges. For real-time intraday tracking, use your exchange directly. For portfolio-level tracking, a 60 second refresh is more than sufficient.
Can I track altcoins beyond the top 100?
The searchable dropdown shows the top 100 coins by market cap. You can still manually type any ticker symbol and if CryptoCompare supports it, the price will populate on the next refresh. Very obscure coins may show zero or no price, in which case the portfolio value for that holding shows as zero.
Can I export my data?
Yes. Click the Export CSV button to download a file containing every holding with symbol, amount, buy price, current price, value, 24 hour change, and profit or loss. This is useful for backup, tax preparation, and importing into spreadsheets.
Can I import from Coinbase or another exchange?
Not currently. The tracker is purely manual entry. Automatic import would require connecting to exchanges via API, which inherently breaks the no-signup, no-tracking privacy promise. If you want automatic import across exchanges, a service like CoinTracker, Koinly, or a dedicated portfolio app is a better fit.
Does this tool do tax reporting?
No. The tracker shows current value and a simple profit or loss based on buy prices, which is an approximation only. It does not track individual trades, does not handle taxable events, and does not know about lot-specific cost basis. For tax preparation, use our tax calculator for rough estimates, and a dedicated tool like Koinly for formal filings.
