Hardly anyone, as long as the price is so low, will pay with Bites or even Blackbites, which you first had to buy laboriously.
And if the price rises, nobody pays with crypto anyway if they don't have to.

And what should the merchant do with the Bites? To switch to Fiat in an awkward way? Why would he want to do that?

No, dear ones.
Regulated trade relies on Fiat.
Unregulated trade uses Crypto.

The crypto world is a niche, so focus on that niche and don't get bogged down in mischief.
