What This Workflow Does
This workflow takes messages from Telegram users asking about cryptocurrencies.
It sends these questions to AI systems that use CoinMarketCap APIs to get live data about coins, exchanges, and decentralized exchanges.
Then it writes an easy-to-understand answer and sends it back on Telegram quickly.
The system keeps track of conversations so answers relate to previous questions.
This saves time and prevents errors from checking many websites manually.
Who Should Use This Workflow
This is made for cryptocurrency traders and analysts who want quick updates without searching many sites.
People using Telegram for chatting can get instant crypto info with less effort.
It helps those who find manual crypto data chasing slow and confusing.
