With so many discussions and resources, and so many subchains and protocols within the ethereum network, how will i know a good place to start?

Do i want to trade through specific chains, using specific protocols? Are some technologies blowing other technologies out of the water? Should i invest in specific coins or projects?

I ask all these questions because i’m coming around to the idea of investing, while also knowing that not all projects on the Eth network are built anywhere near equal. Are there prodigy projects? Front runners? Projects, protocols, or tech of great interest? Should i just invest in good ol’ Eth from the mainnet?

The ethereum network seems to be evolving at a pretty fast pace, and that can make it hard for a noob to discern where to start.

Anything pointing me in a good direction, or towards a good starting point would be appreciated 🙂
