The reason some ICOs release a white paper in LaTeX is that there is often a lot of math to be written out. Take for example IOTA's white paper: https://iota.org/IOTA_Whitepaper.pdf
Often, it's easy to spot the ones that are doing the faux-academic thing.
IOTA's paper was what I was thinking about while reading OPs remark about blogpost to LaTeX conversion.
I'm not sure if I'm dumb, or its dumb (trinary, whaa?) but I had a really hard time getting through it without rolling my eyes a whole bunch. I still have 77 MegaIOTA, just in case someone ever figures out a use for it.
