General estimation only, and rules differ enormously by country. The point is to show you what to set aside now.

The timing trap
If you made large gains in one tax year and lost it all in the next, you can owe tax on the first year that you no longer have the money to pay. This has genuinely ruined people. Set the tax aside when the gain happens, not when you withdraw.
Swaps are usually disposals
In most countries swapping one token for another is a taxable event even though no fiat was involved. People who never withdrew a penny have still owed substantial tax.

Common questions
Do I pay tax if I never cash out?
In most countries yes. Swapping one crypto for another is usually a disposal and therefore taxable.
Can I offset crypto losses against gains?
Usually yes, but not everywhere. India taxes gains at 30 percent with no loss offset at all, which makes active trading there uneconomic.
