The risk of the companies disappearing may indeed be low. One historical fact does come to mind: the St. Petersburg stock exchange reopened in 1917 (after being closed for world war 1), then closed two months later because of the Russian Re

The reason I said "it's important to look at the order book" is because otherwise you might enter a market order and expect to get something near the last trade price. Which you won't. I do think the "correct price&

One interesting thing about "highest bid" and "lowest ask" prices is that they can sometimes move up and down for days without a transaction ever happening. This can be observed in certain illiquid markets, e.g. for a s

The core bitcoin wallet has a "signmessage" API call that can be used to sign a message with the private key behind an address, thus proving ownership of the address. So it seems to me that by this logic, the core bitcoin wallet a

I think font selection is important to make it a fair comparison. For each language, the minimal resolution "pixel font" that still works should be used. (E.g. Chinese hanzi are going to require more resolution than the latin alph

That makes sense. It would indeed be simpler to make the buoyancy volume variable in that case. I'm not sure though that fabrics exist which are both stretchable and can hold on well to small molecules like helium. (e.g. mylar can be s

It's the opposite for us; I'm the one feeling cold, while my wife is comfortable. I started wearing a layer of thermal underwear in the cold seasons to compensate.

Within the event horizon of a black hole, spacetime seems capable of "moving" towards the center faster than the speed of light. That's why light cannot escape, right?

This energy miracle may be a bit of a short lived illusion. The shift to fracking also resulted in a much lower EROEI (energy return on energy invested). Quote from [1]: > Two aspects of shale production make it radically different from
