(there isn't a window fallacy we can't broken here :D)
As stated in another comment, a coin only needs to sell one unit, and because of the supply; they have a large market cap.
IMHO, it's certainly below 3.8%
I would like to know which distribution you sample from :-)
What I meant to say, is that if we look at the coin graveyard, we are including 100% of the failed coins -- because ICO were heavily publicized.
If we look at the startup survival rate, we are not including 100% of the attempt. Some will consume money, but never even make a blip on the radar.
If you consider the failure rate of startups vs the failure rate of ICOs, I think ICOs show a higher success rate - and even more when you raise valuation.
Here is a more extreme example: A startup valued over 1 billion is a unicorn. An ICO valued over 1 billion is at the moment (with rock bottom prices) anything above the top 18
We can disagree on the valuation formula (fair critic), but even with that a 4% success rate >50M is nothing to sneer at.
It's possible to see failed startup if we use figures from an accelator, like say YC.
From https://blog.ycombinator.com/yc-portfolio-stats/ :
Number of YC companies worth more than $100 million: >20
Number of companies funded by YC so far: 716
Let's say 20, and use the $100 million instead of the $50M as I can't quickly find YC numbers for $50 million.
Still, 20/716 is about 2.8%
So I repeat my words: a success rate of 3.8% is wonderful.
