I like crypto, but damn it's inefficient and costly.
Even the crypto that's newer than Bitcoin (all of it?) and therefore more efficient (not proof-of-work/stake?) is still not efficient in cost/time/other-resources/etc.
That is the best part of today's blockchains - huge space for improvements! I don't see the same opportunity in centralized services/protocols which are kind of "done" and control by few big tech companies with so many resources, which they use to keep that control.
