For years I am watching the cryptocurrency Nano ($XNO). As many cryptocurrencies, it is free / libre / open source, decentralized (belongs to no nation). But it is also totally without fees (I haven't believed it but checked and it is really true), super fast (full confirmation under 1 second) and super energy efficient (on par with usual bank card transaction). And the guys beyond it are there for the original goal of crypto - enabling independent money usage - while also explicitly distancing themselves from speculative "investing".
But it is not yet "commercial grade", so big companies are for now not encouraged to use it for high throughput use cases. And it is also not yet widely accepted by vendors, and widely owned by paying customers. Basically the chicken and egg problem...
