All these blockchains including TAU are seriously working hard on releasing more of their product and solving a lot of problems of any current system.
10 months ago the prices didn't reflect the development of each project but now, the prices doesn't reflect the progress of these projects as well... hahaha...
The valuation that is coming is gonna be massive. I'm not invested in TAU but you talk about it a lot that I'm looking at it and wanting to study it much closer.
RE: Demo coming soon? Tau Meta Language in C++ updated on Github.
