Bybit covered $1.5B last year, so it shouldn't be surprising that Binance, a much larger exchange, is able to cover 4x more.

I think people here underestimate how profitable these exchanges are.

These companies are selling subscriptions for what is basically AGI, yet you think they should have the same valuation as Crocs (yes, the footwear company) ?

If the goal is just to buy and hold, then you wouldn't use perps, not only because of counterparty risk but also because the funding rate is typically positive, meaning you pay (usually ~10% APR) to be long.

The point of perps is:

- Easy access to leverage. Unlike options or futures, there's no need to roll over.

- It's the easiest way to short a coin. Most of the time you even get paid the funding rate to be short.

- Trading fees are typically much lower than for spot.

- Volume and liquidity can be better for perps than for spot. The BTC/USDT perp did 10x the volume of the spot pair in the last 24h on Binance.

But formalization is the easy part for humans. I'm sure every mathematician would be be happy if the only thing required to prove a result was to formalize it in Lean and feed it to the AI to find the proof.

The methods are know, but the solutions to the IMO problems weren't. So the AI did extrapolate a solution.

Also, there's no reason to affirm that an eventual cure for cancer requires fundamentally new methods. Maybe the current methods are sufficient, it's just that nobody has been "smart" enough to put the pieces together. (disclaimer: not an expert at all)

So how do these huge buybacks actually work? Like, do they just buy them in the open market? Or is it all OTC?

New comment by trotro in "The economics of American lotteries"

trotro — Fri, 05 Apr 2024 12:44:03 +0000

Notwithstanding the extremely low probability of winning, lotteries aren't even fair, i.e. the ticket price is far lower than the expected earnings. I wonder if it would make sense to democratize cheap high risk, high rewards instruments, for example deep out of the money options, to replace lotteries. At least their prices should be fairer (under the efficient market hypothesis).

New comment by trotro in "Binance lays off over 1k Employees"

They don't depend on the blockchain, but the fact is that most recent research on these topics has come from the blockchain/cryptocurrency space.

One interpretation is that crypto companies need security and privacy, while big tech doesn't seem to care all that much.

I know this is tongue in cheek, but there's a lot more to crypto than the scams and failed projects exposed on web3isgoinggreat.

One example is all the amazing new research in zero-knowledge proofs, MPC, FHE, and modern cryptography in general, that is motivated and funded by cryptocurrency projects.
