Notice how Vigna and Casey in their book The Age of Cryptocurrency use dashes in the following paragraph. The first two dashes set apart an adjective clause. The third dash introduces a participle phrase.

The team also planned a fund-raiser. Described as a “presale” of ether, Ethereum’s special internal currency—which in compliance with Swiss law was described in the fund-raiser not as a currency or a security but as a piece of software needed to run future applications—the offering raised more than twenty-nine thousand bitcoins, worth more than $14.5 million in late August. By that measure, and considering the relatively short six-week period, it’s fair to say it was the most successful crowdfunding exercise in history—beating anything else that’s even been done over platforms such as Kickstarter.

Note how Morgan Housel in his book The Psychology of Money uses a dash in the final sentence of this paragraph:

A hyper-connected world means the talent pool you compete in has gone from hundreds or thousands spanning your town to millions or billions spanning the globe. This is especially true for jobs that rely on working with your head versus your muscles: teaching, marketing, analysis, consulting, accounting, programming, journalism, and even medicine increasingly compete in global talent pools. More fields will fall into this category as digitization erases global boundaries—as “software eats the world,” as venture capitalist Marc Andreesen puts it.

Notice how Robert D. Putnam in his book Bowling Alone uses dashes in the final two sentences of this paragraph:

While Americans are spending less time doing sports, we are spending more time and money watching sports now than we were only a few decades ago. Sports spectatorship has been rising rapidly, which helps explain the rapid rise in the salaries of professional athletes. In part, the growth in spectatorship reflects our television viewing habits, but it is also reflected in live attendance figures. Adjusted for population growth, attendance at major sporting events has nearly doubled since the 1960s. The year-to-year fortunes of individual sports have varied with the excitement of the season and the vicissitudes of labor-management relations, but virtually all major sports have seen grown in per capital attendance over the last four decades—professional baseball, basketball, football, hockey, and stock-car racing, as well as college football and basketball. Figure 27 summarizes this trend—at last, a trend line that is rising, if only for the passive spectator.
