Yeah I saw something fly by on my feed that they were responsible for big btc dumps https://x.com/1914ad/status/2026757796390449382 Haven't read it yet but seems spicey

Appreciate the noise filter.

Who would've guessed - a dip in price means more sellers than buyers :mindblown:

All I think when I see this is "this intelligence wasted on finance and ads." Can you imagine human potential if it was somehow applied to crop harvesting efficiency, new medicines, etc? Not everything has to be perfectly efficient but it just saddens me to see all these great minds doing what, adversarially harvesting margin from the works of others?

I like that Jane Street hires smart people and supports cool initiatives like ocaml.

But don’t fool yourself, they don’t make their money with intelligence.

They just do fees and insider trading.

There are much much more great minds working on new medicines than on HFT. Also HFT is good, it makes world better place!

What exactly is the point of making a unverifiable statement(s) like this?

Fwiw on the ETF side they're talking about IBIT/GBTC etc which only a tiny number of "authorized participants" are able to mint and redeem vs BTC.

I'm really curious what were the magic words. > Alex had actually tried to brute force the hash earlier, but had downloaded a list of the top 10,000 most popular words to do it, which turned out not to be big enough to find it. Once he had a big enough word list, he got the answer. They don't reveal the answer.

If I had to guess, “hot dog” would be the first thing I’d try. “Vegetable dog” was given as 0, and it may be alluding to a Silicon Valley episode.

To better understand your thinking here, can you illustrate for me a scenario with less liquid markets because firms like JS are less efficient at making them, and the knock-on effects?

We already have very efficient crop harvesting and Eli Lilly is nearly a $1 Trillion dollar company. Interestingly, the new medicine is designed to keep us from eating so many cheap calories (new weight loss drugs). > Not everything has to be perfectly efficient but it just saddens me to see all these great…

I think the comment was a roundabout way of saying this is a clear market failure. There are more societally important things these people could be doing instead of shaving another ms off a transaction or finding minuscule option pricing inefficiencies. That the market is not correctly remunerating those options is the failure. > For example, the tariff tantrums caused by trump proposing 100%+ china tariffs where he…

this undervalues how financial engineering allows more ideas and companies to be funded

compound interest is a rare exponential force, and it is available to most citizens of a developed country through the stock market

financial futures remain important for farmers to have predictable pricing, and increase crop yields

science is limited by funding at least as much as it is limited by ideas or intelligence

I understand why finance is a popular bogeyman, but the world is rarely black and white
