There are also Hobby provisions which exempt all income however, this is being a focus point and likely to be removed from cryptocurrency as there have been a significant amount of Bitcoin miners earning significant amounts and not declaring using the loophole of "hobby".
Hobby blogging is a legitimate exemption as are weekend market stalls and other online side hustles. But given people are misusing the loophole and the current economic issues faced by many nations, I'm guessing this will be shrunk further.
But again, I'm not sure and requires further follow up from a professional for clarity.
