Oil does not come from dead dinosaurs. The fossil fuels, the name given as such, originates from commitment of oil producers to make it appear as scarce.
"Most oil reserves were formed between 65 and 252 million years ago. While this does overlap with the ‘dinosaur times’, oil is a marine sediment made of the remains of algae and plankton.

Skeletons of prehistoric reptiles such as plesiosaurs and ichthyosaurs (neither of which count as dinosaurs) have been found in the same geological layers as oil and they may have contaminated the oil deposit. But to say that oil is made from dinosaurs is like saying that bread is made from insects, just because the odd one occasionally falls into a flour mill." - www.sciencefocus.com/planet-earth/dinosaurs-in-fossil-fuel

Important to note, many "depleted" oil wells replenish themselves over time.

A fun thought experiment on SN is to have everyone live list their failures in a day to normalize that we all fail all the time. Now I'm trying to think about how my last failure was probably not the last and I've got hundreds more recent than that lol.

We succeed by failing until we succeed or by getting lucky

There's a chance that it's not failures that define anything but rather forming your life around trying a ton of things with a specific percentage chance. If you took an action that took one year and had a 60% success rate at something huge, vs something that took a day and had a 1% success rate as something huge, the ones that take the smallest amount of time, thus a person makes the most amount of failures, is more about what defines eventual success.

I think about this a lot when it comes to MVPs in a startup.

Depends on which exchange. Exchanges with order books like coinbase, kraken, etc just get their bitcoin from customers, people buying and selling fill out the order book. Exchanges like River, Swan, Strike, etc are brokerages and get their bitcoin from market makers and other services. Lots of these services just have accounts on the other exchanges and buy at whichever has the best price.
