An "all" statement is very dangerous to make, because it puts quite a stretch on how certain you need to be of your claim (or "thought").
In this case, it's just a ludicrous ps://t.co/1KjwDK6wVL
That means making choices about what you can and cannot do.
So you forego certain things.
Not because I've seen them, but because it's just logically a really open and unverifiable claim.
They *may* be ICOs that were bona fide and good.
Haven't seen too many that are on that path, but who knows?
It's just too broad to have any meaning, making the statement useless and suggestive.
Because that's what it implies.
