Who among us here have been victims of almost perfect Whitepaper?
Those sublimely well-written, full of excellent ideas and proposals that turned out to be a piece of crap!
Reading whitepaper is not enough to be a basis of investing in crypto because almost everyone can write whatever they want,
they even promise you the Moon and Stars.
So, be careful now in choosing ICOs, as much as possible look for projects that at least have initially implemented the products or services, if not the whole. 
I guess Whitepaper is just a par t of significant things in the ico to become successful, then in my perception I think the company profile of the
company in the ico is what matter most, from the Founder/CEO, team behind the company, also their good background or etc. something like
that which I think is the important matter anyway.
