No, I didn't build an exchange bot.

I built a tool that helps people convert different currency amounts into Byteball amounts. For example, you can use that tool to ask somebody to send you 10 STEEM in bytes or 0.001 BTC in bytes or 5 USD in bytes by just sending them the link with your Byteball addres or scanning the QR code.

So, it is not exchange, just a tool to ask somebody bytes in certain amount in any other currency. Shop owners could easily enter amount in local currency value they want and they could receive that in bytes by showing the QR code to customer, but they would still need to exchange it to their own currency later.
