heya bigga bigga P,
I am apart of a web3 community, but that doesn't mean we are crypto community. Web3 means decentralization, which really just means distributive ephemeralization (doing more with less). I don't trade crypto.
Considering we've been developing our body of work for well over 10 years, forcing all of us to lose everything at one point, no i can say personal wealth not the motivator.
Our focus in terms of technology design is building mutually resolving consensus platforms.
"Saving humanity" quite a tall order, solving small problems one at a time is more where we are focused.
