CryptAPI API

// Fetch current cryptocurrency prices

top5.forEach(coin => {
  console.log(`${coin.name || coin.symbol}: $${coin.price || coin.current_price}`);

// Track portfolio value with current prices
const holdings = { BTC: 0.5, ETH: 2.0 };
const response = await fetch(`https://docs.cryptapi.io`);

  console.log(`${symbol}: ${amount} x $${price} = $${(price * amount).toFixed(2)}`);
});
console.log(`Total portfolio value: $${total.toFixed(2)}`);

// Monitor price and trigger alerts
