The sheer scale of these potential frauds - including the total ambiguity of massive $ raised for ICOs is not only consistent with the shenanigans of the .com - it's much worse.
In .com - companies were creating value, and we all assumed people would pay for 'email' - turns out consumers would not - so many businesses failed, and there was a stampede out of equities.
All of this coin and ICO fraud, including 'regular company' valuations of 300x P/E rations - is absurd.
In 2000 - the bubble was popped with a little bit of an interest rate hike that caused major funds etc. to scramble, causing a stampede.
Markets are definitely emotionally positioned for a black-swan event to cause a scramble.
The markets have to correct for all this sketchy/possible fraud going on.
