Can you buy on Etrade?

Excuse me, I'm a bit new to the world of investing and I'm curious about the options available for purchasing cryptocurrencies. I've heard of Etrade as a platform for traditional stocks and bonds, but I'm wondering if they also offer the ability to buy cryptocurrencies? If so, what kind of cryptocurrencies can I expect to find on Etrade, and what are the fees and requirements associated with making such a purchase? Additionally, are there any alternative platforms you would recommend for those looking to invest in cryptocurrencies?
