Is NiceHash taxable?

Hello there, I'm curious about the tax implications of using NiceHash, a popular cryptocurrency mining marketplace. As a cryptocurrency enthusiast, I've been earning some passive income through NiceHash by renting out my mining power. However, I'm unsure if this income is subject to taxation. Could you please shed some light on this matter? Is the income earned through NiceHash taxable, and if so, what are the specific tax rules and regulations that I should be aware of? Thank you in advance for your help.
