How can you say it's clear it wasn't cash? What's the source? Also, FTX minted FTT out of nothing - effective cost zero - so no matter what they received in exchange, even if they had received nothing that is not an investm

Nowhere does it say that FTX invested in Alameda. Alameda invested in FTT which is minted by FTX which is not the same thing.

SBF said "We don't invest client assets (even in treasuries)". [0] He then says the purpose of the transaction with Binance is to "clear out the liquidity crunches". [1] How could there be a liquidity crunch if asse

I get a couple of gallons of olive oil in a small village directly from the press in November each year. It's not filtered so it has a lot of particles in suspension and it goes bad faster, maybe after a year or so. But it tastes nothi

The fact that they closed his account frankly sounds like the outcome of an AML review. Banks are deputized by the government to check for all sorts of suspicious transaction. They get fined when their procedures are not sufficiently string

Fuel cost, depending on routes, number of business seats, seat occupancy is at about 25% of total costs [0]. 75% is what you call epsilon? Aircraft speed as barely budged since we transitioned from turboprop to jets. That's something y

That doesn't have much to do with the point I'm making. I'm saying if you double fuel usage, you don't double the cost of using the plane. As cost of fuel is only a percentage of the price of the ticket, it's pretty

To everyone saying this will not work because it's more expensive... jets were more expensive than turboprops. And even though the former use more fuel, we prefer them. The costs of flying an airplane isn't proportional to its fue

Well this article seems to be about the opposite of that, less precise than necessary or slightly outside of tolerance range!

I thought biomass was marginal but you actually produce almost as much electricity with biomass as with natural gas. I stand corrected. https://en.wikipedia.org/wiki/Electricity_sector_in_Germany

1. Your article on nuclear energy just says that France has reactors that need maintenance. It also says they produce less electricity because they need cold water which is not currently available because of heat waves and droughts. Both ar

Nuclear is obviously key to energy independence etc... but the very common take these days of "Nuclear power is the safest energy production technology available, just look at historical data" is deeply misguided. It's very h

I understand that energy consumption includes things that aren't electricity so the proportion of oil is higher but everything else is different too. For example, in the parent comment, more wind than biomass is produced but in this co

South Africa has 20,000/day cases which is about the same they had in July, yet they peak at 30 deaths/day vs 400 deaths/day in July. To estimate the fatality rate of a variant, you need to do it within the same population. A

Not really. If operational expenditure decrease while capital expenditures stays constant, it could still cost the same amount of money to mine but use less electricity. A miner pays both for power and the mining rigs.
