Is there a maximum of Hbits to be mined?

Max is 21 million, just like Bitcoin. The max, by the way, for the other tokens in Wusang can be seen at https://wusangisleofblaq.netlify.app/pages/play.html - they're even more rare.

At how many we're at the moment?

For HBIT, 40,000. See https://tribaldex.com/trade/HBIT and click the "i". For the other BLAQ tokens, I went ahead this morning and issued the max amount to the @hivebits account. I debated whether to release them all or not, but I didn't want one of them to run out and the "well to go dry." Those tokens will sit there and only be released by the wusang bot as they are found. Since we are only one day into Wusang, the following have been found:
BLAQ: 26
BLAQGOLD: 10
BLAQEMRDLD: 1

And what are you going to do when that maximum has been reached?

When they're all mined, they're all mined. There are no more...finite scarcity at its best!

Have you got any plans for that?

I can't do anything then. The only way to get those tokens then will be on the open market.
