For converting money and checking official rates, In/Into Exchange Bot (@inintobot) is the better tool: you choose the rate source with /apis, including the European Central Bank, ask for any past date and use it inline in any chat. CoinTrendzBot (@CoinTrendzBot) answers /rates with a live rate for a currency pair, but that is one command among about 60 aimed at crypto traders, and the free version carries ads. It is the right pick for a trading group that wants currency rates, crypto prices and stock quotes from a single bot.

A currency converter that goes further than most: several rate sources to choose from, including the European Central Bank and the national banks of Belarus and Ukraine, historical rates for any date, weekly history for a pair, and inline mode in any chat. Free, English, and updated through 2026 by its author.
A market-data bot for chats and groups: /p for a crypto price, /c for a chart, /sp for a stock price and /rates for a currency pair, among about 60 free commands. The free version carries ads; Pro at $125 a year removes them and adds price and RSI alerts. Running since 2017, about 12,000 users a month.
