The original comment addresses that concern:

>Why in the absence of any positive evidence, like "oh here is our genius but nonetheless expired" trading strategy, which anyone could have furnished in the last two decades, they agree, oh it must be real?

I agree that there should be some obviously awesome things these funds did that they can share now given they are no longer able to exploit them. I have no idea if they have done so and I and GP are just not aware of it.

That is part of it. The Sequoia piece[0] describes what kicked off Alameda Research: after a tumultuous hard fork, there used to be a discrepancy between the price of Bitcoin in JPY at a Japanese exchange, and that in a US exchange. So he opened a Japanese account, bought a bitcoin in the US for a low price, and sold it in Japan for a high price.

To be clear, it is described by SBF. I haven’t verified historical prices to confirm it. The journalist that wrote this article probably hasn’t either.

He claims to have been wiring $25m a day from a BoA branch to banks in rural Japan. Total horseshit.

And at least in SBF/Alameda's case, they did, and you can google it. IIUC it was basic arbitrage, the hard part was figuring out how to interface with Japan's banks.

Maybe the guy is a bad dude, I don't have a horse in that race. But lots of trading strategies that have worked in the past are well known.

There are known expired strategies that generated large profits for long periods of time. In some cases the people involved in developing the strategies have directly published things explaining what they did.

Do you have any examples? Would be interested to read sone

[elijaht]

Article mentions one (bitcoin arbitrage)

[taliesinb]

I'd be fascinated to read these published things if anyone can point to them!

The books and articles by Ed Thorpe are a good place to start.
