Of course, not every ICO needs whitepaper long for PDF 35+ pages.
Do you think salesman selling burgers and who invest in crypto, is going to read 35 pages, full of technology jargon? Even, person who wrote such whitepaper do not understand it...
However, I would like to see clean FAQ page(s) packed with crucial information of the project.
Hope this crayziness with ICOs will be over and we will see sensible projects (in less quantity) popping-up.
At the moment, I stopped investing in ICOs.
