Help with Tax Treaty Interpretation

Sprintax is claiming that due to the following treaty article, I should be taxed at 0% for my crypto capital gain.

I am a non-resident for tax purposes (< 5 calendar years present in the U.S.) but have been present in the U.S. for more than 183 days during the tax year.

If I'm interpreting (c)(ii) correctly, I should be taxed at the default 30% and not 0%. Is my interpretation correct?
