How much capital gains tax do I Owe for crypto?

Could you please elaborate on how I can determine the amount of capital gains tax I owe for my cryptocurrency transactions? I've been actively trading various digital assets over the past year and I'm concerned about my tax obligations. I understand that the tax treatment for crypto varies depending on my jurisdiction and the specific nature of the transactions, but I'm looking for a general guideline on how to calculate the tax owed. Is there a specific formula or methodology I should follow? Also, are there any common pitfalls or mistakes I should avoid while calculating my crypto capital gains tax?
