Do I pay taxes on cryptocurrency?

Good day, fellow investor. I've been delving into the realm of cryptocurrency recently and I've come across a rather perplexing question. As the value of my digital assets continues to fluctuate, I'm wondering: Do I actually have to pay taxes on the profits I make from my cryptocurrency transactions? Is there a threshold I need to surpass before I'm liable for taxes? And how do I even calculate the taxable amount? I'm hoping to gain some clarity on this matter as I continue to navigate the complex world of cryptocurrency investing. Thank you for your time and assistance in this matter.
