/**
 * LARGER BACKEND PROJECT STRUCTURE
 * If this were part of a production Node.js application, I would structure it as follows:
 * * 1. Service Layer (`/services/cryptoService.js`): This file. It isolates the 3rd-party API logic.
 * 2. Controller Layer (`/controllers/marketController.js`): Handles incoming client requests.
 * 3. Caching Strategy (`/utils/redisCache.js`): Crypto APIs have notoriously strict rate limits. 
 * In production, I would cache this data in Redis for 30-60 seconds to serve thousands of 
 * users without getting banned by the API provider.
