Should I just focus on Ethereum or continue to invest in Bitcoin?

I'm relatively new to the Crypto world. So far, I've been investing in both Bitcoin and Ethereum at a roughly 50/50 split.

At the moment, it feels like there's a lot of development on the Ethereum network (DeFi, Web3, etc.) whereas Bitcoin simply appears to be a store of value.

Is there any point in continuing to invest in Bitcoin? Should I solely focus on Ethereum instead? I'm looking for advice from a purely investment point of view.
