Oh alright. I don't see how this invalidates the use cases? The businesses that have payment processor problems aren't illegal, and can easily prove their revenue.

And I do agree that unsustainable systems don't collapse immediately. I've been waiting for Tether to collapse for years. But I don't think cryptocurrencies as a whole are unsustainable (the larger proper exchanges that don't use Tether as their "fiat option" should survive).
