Are all Cryptos available on Coinbase?

Excuse me, I'm curious about the availability of cryptocurrencies on Coinbase. Could you please elaborate on whether all cryptos are accessible through this platform? I've heard that Coinbase is a popular choice for investors, but I'm wondering if there are any limitations in terms of the variety of cryptos offered. Would it be possible for you to provide a brief overview of the cryptos that are currently available on Coinbase, and perhaps mention any notable exclusions? Thank you for your time and attention to this inquiry.
