An inline converter by developer nitanmarcel: type @currconverter_bot 20 euro in usd in any chat and send the answer as a message; its start message claims over 1,000 real and crypto currencies. Free, but the open-source repository was archived in 2023, so nobody is updating the bot.
Currency Converter (@currconverter_bot) is an inline bot: you type its username in any chat followed by a query such as "20 euro in usd" or "how much is 20 euro in usd", and Telegram shows the converted amount to send as a message. Its start message says it supports over 1,000 currencies, both real-world and crypto, and suggests trying the query again if nothing comes back. There is nothing to configure and no account.
The developer, nitanmarcel, published the code on GitHub under the MIT licence and links it to this bot. The repository has been archived since July 2023, and the README contains only screenshots and donation links, so there is no public description of where the rates come from or how often they update.
That makes it a quick way to get a rough figure and not much more. If a result looks off or the bot stops answering, there is no maintainer to fix it; for rates you can cite, a converter with a named source is the better choice.

The bot and its README do not say. Treat results as an estimate and check an official source before paying.
No. It works inline, so anyone can type its username in any chat without adding it.
