Do you have to pay tax on Coinbase?

Good day! I'm curious about something regarding cryptocurrency and taxes. Could you please clarify for me: when using Coinbase, a popular cryptocurrency exchange platform, am I obligated to pay taxes on the transactions I make? Specifically, do I need to report any gains or losses from buying and selling digital currencies through Coinbase to the relevant tax authorities? And if so, what kind of taxes would typically apply? I'd appreciate any insight you can provide on this matter. Thank you in advance for your time and expertise!
