So far, Tether has only given the market transparency around exactly four days each year.

Why it matters: Tether is the third biggest cryptocurrency in the world, with a $67.5 billion market cap, and it's the most widely traded against the biggest cryptocurrencies, such as bitcoin and ethereum.

In the four years that he led the Defense Innovation Unit, tasked with bringing the fruits of commercial tech world to the U.S. military, Michael Brown says he added more than 100 new vendors to the Pentagon roster.

Yes, but: Brown tells Axios that the Pentagon needs to make more structural changes in how it buys equipment if it really wants to take advantage of commercial technology.

It's going to take more than a months-long cryptocurrency free fall to squash the mounting ransomware problem, cyber incident responders and threat analysts tell Axios.

Why it matters: Companies have been struggling to fight off an abundance of ransomware hackers in recent years, but recent optimism over a crypto-crash-fueled drop in attacks might be short-lived.

I took an electric Volvo C40 Recharge on a road trip to fly-fishing country in northern Michigan last weekend.

Why it matters: I found out EV road trips are completely doable. You just have to plan ahead.

Details: Some friends invited my husband and me to their cottage along a stretch of the Au Sable river known as the "Holy Waters" for its incredible fly fishing.

• Their place is about 215 miles away from my home — technically within the Volvo's EPA-estimated range of 226 miles. But those numbers don't always equate to real-world performance, so I wasn't going to take any chances.
• I knew from talking to auto industry folks that a fast-charging station in the parking lot of a giant Meijer store just off I-75 in Bay City was a popular charging waypoint.
• I confirmed the location and directions with the embedded Chargepoint app on the Volvo's center touchscreen, which lists all available charging stations. The Plugshare app on my phone was another helpful resource.

How it worked: We left home with 92% battery range, good for 204 miles, according to the car's instrument panel. Two hours and 120 miles later, we exited I-75 at Bay City, with 37% left on the battery.

• The chargers were easy to find at the east end of the Meijer lot: there was a Tesla Supercharger station (with eight plugs) and an Electrify America station (with four).
• Anyone can charge at Electrify America, but Tesla's Supercharger is reserved for Tesla drivers. Both stations were busy, but we didn't have to wait.
• I swiped my credit card, plugged in the Volvo, and walked across the lot to do some shopping.
• By the time we returned, the car had charged from 37% to 86% in 36 minutes, which cost $19.14, including tax.
• Interestingly, a comparable gas-powered Volvo XC40 gets 30 miles per gallon, so that 120 miles would have cost less — $15.76, at Michigan's current $3.94 per gallon average gas price.

When we arrived at the cottage, we had a solid 44% left on the battery and decided to go kayaking, knowing we'd have to find a charger again the next day.

• There were several charging options in the small town of Grayling about six miles away, so we decided to hit a local brewery while we waited.
• Our trip home to Detroit was similar, but in reverse — we charged up again at Meijer and walked across the lot to grab some burgers at Culver's. Thirty minutes later, we had 180 miles of range (82%) and were ready to hit the road again.

What's needed: It struck me that freeway signs should add a symbol for upcoming EV chargers, like they do for food, gas, and hotels.

The bottom line: My 425-mile road trip in an EV was remarkably stress-free.
