>in a similar vein, what could use somebody's web skills is a ICO fraud site that looks as impressive and overengineered as ICO marketing sites (case in point: IOTA https://iota.org/. not commenting on the merits of the project, just the site). although these sites probably already exist.

That site is insane, I wonder how many people don't even make it past the home page because of loading times or some fancy feature breaks. I loathe websites removing basic functionality like scroll bars.
