No exchanger we have come across says less than this one: one line saying you can swap BC for rubles and USDT, and nothing else. No rates, no timing, no support contact. Only use it once you have checked everything with the seller yourself.
The bot works right inside the chat and has no separate mini app. The only listed command is start, so everything else presumably sits in menu buttons after launch. There are two directions: buy BC or sell it, paying in rubles or USDT.
The big mystery is what BC actually is. It might be an in-game currency, a token from some project or something else entirely, but the abbreviation is never spelled out. If you landed here on purpose you probably know already; a random visitor has nothing to go on.
Also missing is everything you normally look for in an exchanger: a website, terms, who runs the deals and how to reach support. Rates and fees are likely shown inside, yet you cannot compare them in advance. It is a trade with an unknown seller, and the whole thing rests on trusting them.
If you still want to try it, start with a small amount, keep screenshots of the chat and receipts, and ask before paying who sends the other side of the trade and how fast.
