     Its pricing is highly volatile — and therefore highly risky. For all its nosebleed ascents, bitcoin also has had some gut-punching plunges. Between November 2021 and November 2022, for example, the price of bitcoin dropped 75%, from $64,455 to $16,196, according to data on coinmarketcap.com.

   • 2010, Jon Jagger, Nigel Perry, Peter Sestoft, Annotated C# Standard, page 467:

     This method stores a value into a non-volatile field called result, then stores true in the volatile field finished. The main thread waits for the field finished to be set to true, then reads the field result.
