It’s a long list. Decentralized. No CEO or Board of Directors. No marketing. Ultimate scarcity - there will only ever be 21M Bitcoin. Portable. Divisible. Fungible. Incorruptible.

It’s a $2T asset. There is no second best. Take some time to learn. Good luck!!

You know not of what you speak.

There is no comparison between Bitcoin and all the other cryptocurrencies. Spend some time learning the difference.

The pictures are from the old Bahrain Fort, a tourist attraction, about a 20-minute drive from the US Naval base (just for accuracy’s sake).

Solitary rugose coral and crinoids. Mississippian or Early Carboniferous.

Yes, they’re common marine invertebrate fossils since the Cambrian. At times they were major reef builders.

Merely pointing out that all energy sources have costs and trade-offs. People think that the electricity for EVs comes out of a plug by flipping a switch, not from burning coal. Wind turbines and solar panels don’t grow; they’re mined.

Clever enough to know that answer (geology professor of 39 years). Simply pointing out that all energy sources have trade-offs.

And the battery and cable raw materials come from? Anyone?

Mining.

But 45-55% indirect cost rate for mediocre facilities and bloated admin undermines the scientific endeavor. So, what’s a reasonable IC rate?

Cash will melt like an ice cube with high inflation.

No. It’s defined as falling on the first Sunday in April. That’s when we celebrate it.

Again, no need to post same-day spoilers.

I left the US symbolically on January 20, 2017. I’m a geology professor who chose to continue my academic career elsewhere. I’ll be retiring soon from my position in Saudi Arabia, with no desire to go back to the US (heading to Thailand). I love the expat life; you can, too.

They used phishing attacks on exchange employees and customers to get their wallet addresses deceptively. They then laundered the Etherium (for example), mostly exchanging it for Bitcoin and spreading it around wallets they controlled. Neither ETH nor BTC blockchains were hacked.

Crypto was not hacked. The exchange it was held on was hacked. Very different scenarios.

Electricity generation is dominated by burning coal and natural gas. Is that difficult to understand?
