TFA really doesn't explain why it is they want such accurate timing.
The only reasons I can think of are to be immune from GPS spoofing (You expect me to believe those signals? They're off by a whole nanosecond!) and to build your own dynamic positioning network by comparing timestamps of all your various vehicles as perceived by each other (I'm 1234.567m from you, and 2345.678m from him, and how far are you from each other?).

At first glance I read the headline as "SEGA Officially Seals Off All Its Arcades".
And I wanna see that story. In 3033 AD, retrocomputing archaeologists open up the sealed arcades, blow the dust off, replace all the electrolytic capacitors...

NASA paid $396 million to SpaceX (in a series of chunks) to develop Falcon 9 and Cargo Dragon. This investment paid handsomely, saving them a lot compared to what they would have paid for equivalent services from existing providers. They similarly invested in Crew Dragon, and will similarly win from that investment. So I expect they're thinking, hey, let's try that same trick again, see what happens. source

Motherboard also say "four months in the summer and fall". But the interval in question is actually July to November, which is winter and spring.

I notice these ATMs can only be used for turning cash into crypto. But not the other way around, because that would be impossible unless you waited at the ATM for potentially several hours for your transaction to clear.

As such, these ATMs offer only one "improvement" over directly transferring money from a bank account to a crypto account online, via your PC or smartphone: here, you go via cash as an intermediate step. In what circumstance could that extra step possibly be an advantage? When you want to obfuscate the trail. In other words, these are only better when you're up to something dodgy.

It's the other way around. From mini to micro, "the leaf-spring was moved from the jack to the plug, ... so that the connector on the less expensive cable would bear the most wear." In mini, the socket on the device would wear out, rather than the plug on the cable wearing out.

How hard would it have been to put "UK" somewhere in the headline or summary?

Yes, the US dollar is already the currency of El Salvador. They discontinued their own currency in 2001 according to Wikipedia.

I believe the problem they're trying to solve is that current international transfer methods such as Western Union take a huge slice and are hugely inconvenient. So it's possible that if Bitcoin takes a moderate slice and is only moderately inconvenient, it might be an improvement.
