What networks are on Coinbase?

As a cryptocurrency enthusiast, I'm curious to know which networks are currently supported on Coinbase, a leading digital currency exchange platform. Coinbase, with its user-friendly interface and robust security measures, has become a popular choice for both new and experienced investors alike. However, with the ever-evolving landscape of cryptocurrencies, it's important to stay updated on which networks are available for trading and storage. So, I'm wondering - which networks are currently accessible on Coinbase? Are they limited to just the major coins like Bitcoin and Ethereum, or does it also include some of the more niche altcoins?
