Sia is one of the few ICO projects that seems to actually work, but it gets zero attention.
The block chain world is absolutely overrun with over-funded over-specced over-engineered boil the ocean projects that will never ship anything usable, solutions in search of problems, stuff that just plain doesn't work for fundamental math/algorithmic reasons, and of course a ton of outright scams. All of these are loud and lean heavy on the hype because they have nothing else. Just keep working and you will emerge once the dust settles. Not saying forget about marketing, but focus more on product.
