Currently it's in alpha testing stage and is using the Testnet coins.

The bot works with Telegram Payment and can accept credit cards via Yandex.Kassa, Sberbank, Stripe, Paymentwall and other providers (see https://core.telegram.org/bots/payments for full list).

You can create such an exchange for yourself in 2 minutes! Set your own commission fee (fixed and/or %%) and sell you BTC for profit.

1775 nodes out of 9616 (18.5%) are currently on version 0.16.3. Upgrade ASAP to avoid possible chainsplit!

Especially nodes running versions between 0.15 and 16.2 need to upgrade as soon as possible. A bug could be exploited to create an invalid block that gets nonetheless validated by these older versions. This makes a chainsplit a theoretical possibility.

A full resync with the latest software (0.16.3) showed that the bug has not yet been exploited. It probably won't happen as it isn't in the interest of the ecosystem, nor is it easy to excecute. But that's no excuse. Upgrade asap!
