Here's a sample of what Claude might return:

Based on your portfolio and current market prices, here's the value of your cryptocurrency holdings as of April 27, 2025: ZK (ZKsync): 69,696 ZK × $0.06051 = $4,217.48 Bitcoin (BTC): 9,696 BTC × $94,361.18 = $914,904,201.28 Ethereum (ETH): 23,456 ETH × $1,803.33 = $42,288,825.48

Total portfolio value: $957,197,244.24 Your portfolio is primarily dominated by your Bitcoin holdings, which represent over 95% of your total portfolio value. Would you like any additional information about market trends or recommendations for your portfolio?
