How to Set Up a Portfolio Tracker
Via Wallet Connection (Read-Only)
- Go to Zerion or Zapper
- Click “Connect Wallet”
- Select “Watch only” or “Read-only” mode
- Enter your wallet address
- The app shows all tokens across all chains
Safety: Read-only mode means the app can only view — it cannot initiate transactions. Your funds are safe.
Via Exchange API
- Go to CoinTracker or Koinly
- Select your exchange (Coinbase, Binance, Kraken)
- Generate API keys on the exchange (enable “Read” only — never enable “Trade” or “Withdraw”)
- Paste the keys into the tracker
- Transactions import automatically
What to Track
| Item | Why |
|---|---|
| Total portfolio value | Know where you stand |
| Asset allocation | Are you too concentrated? |
| Unrealized P&L | How much are you up/down? |
| DeFi positions | Lending, farming, staking balances |
| Transaction history | For tax reporting |
Verdict
For most people: Zerion for daily portfolio tracking (free, connects to wallets, shows everything). CoinTracker or Koinly for tax season (imports from exchanges, calculates gains).
Track your portfolio monthly. Review your allocation quarterly. Rebalance if needed. Don’t check daily — it leads to emotional trading.

Staying on top of your portfolio
A tracker is only useful if you actually check it. Most people either obsess over daily price swings or ignore their portfolio entirely — both habits cost money.
Review your portfolio monthly for a quick sanity check: Are any positions dangerously oversized? Has something you bought gone to zero? Monthly reviews catch problems early without creating the anxiety that comes with watching charts every hour. Quarterly is the right cadence for rebalancing, which means selling what has grown too large and buying what has shrunk.
Set a calendar reminder on the first of each month. Open your tracker, spend five minutes scanning your allocation, and move on. The people who build lasting wealth with crypto treat it like a chore, not entertainment — they check in, make adjustments, and get back to living their lives.
