Which crypto network should I use?

Hello, I'm new to the world of cryptocurrencies and I'm wondering which crypto network I should use. I've heard about Bitcoin, Ethereum, Litecoin, and many more, but I'm not sure which one suits my needs best. Could you possibly provide me with a brief overview of each network, highlighting their key features, security measures, transaction speeds, and any other important factors I should consider? Additionally, I'm also curious about the potential growth and adoption of these networks in the future. Could you shed some light on these aspects as well? Thank you for your time and assistance.
