Prerequisites

• No browser required — uses CoinGecko's public market-data endpoint

Notes

• The public endpoint is rate-limited; retry briefly if you hit transient HTTP 429 responses
• All numeric values are denominated in the selected --currency; coin fails fast if CoinGecko returns no market fields for that currency
• change24hPct is a raw percent (e.g. 2.34 means +2.34%), not a fraction
• --limit is validated upfront and rejected with ArgumentError if non-positive or above 250 (the CoinGecko per_page upper bound) — no silent clamp
