After getting the basics and after hodling for some time, and now willing to enter the space. I am a mobile/web developer (have been for the last 10 years) but I am having a hard time where would it be the best place to start.

On one hand I am attracted by the BTC ethos and ecosystem, on the other hand the ETH/Solidity space seems fun and more friendly for a standard fairly good web/mobile developer with expertise on Vuejs & Flutter techs (as an example).

I am afraid I would not be of much help in the BTC space…
Where would you start?
What are the pros, cons of each?

Consider optimizing for being and feeling the most useful and really contributing as at this moment I am not really optimizing for money or getting paid much as a web3/dev or anything alike.

Thanks for your help!
