Sounds like a camouflaged IQ test for the founders...
Or perhaps Y Combinator is great at funding startups, but incredibly bad with financial decision making.
In which case it is an IQ test for Y Combinator, which they have failed.
This isn't meant to be cynical. But, two of YC's success stories, Stripe and Coinbase, has a stable coin product.
If you rejected economic orthodoxy and bought Bitcoin/Gold over the last.... decade or so... you won over the economic orthodox believers.
I don't really care about short term gold gambling with ~1-2 year market spans or altcoins if you want to disagree.
The biggest threat to bitcoin and gold is something breaking their scarcity. Gold, nuclear chemistry. Bitcoin... quantum computing or something(ignoring rollback).
One of the biggest YC success story is Coinbase. It has literally got "coin" in its name.
It also trades under the ticker "COIN": https://finance.yahoo.com/quote/COIN/
And after a serious beating it's still value at $48 billion.
Put it another way: of all the companies YC funded, both those who succeeded and the countless who failed, only two companies, AirBnB and Doordash, are valued more than Coinbase.
I don't think YC hates cryptocurrencies as much as the typical commenter on HN.
As with all things cryptocurrency, the goal is to bypass financial regulations and external scrutiny.
