Do I owe tax just for holding crypto?

In most countries, no — only when you dispose of it. Exception: NZ FIF rules may require annual taxation on offshore crypto holdings above NZ$50,000.

What counts as a disposal?

Selling for fiat, swapping one crypto for another, spending crypto, and receiving it as payment are all typically disposal events.
