What's Cryptic About It?
The transaction that sends money from one party to another is digitally signed via public key cryptography. Thus, the identity of the parties is kept secret, much like paying for merchandise with cash in the physical world. However, the transaction itself is a public record; for example, "party x sent 10 bitcoins to party y on June 20, 2015." See cryptocurrency tumbler

Based on Demand
Except for Sharia-conforming OneGram, which is backed by gold, and "stablecoins," which are backed by fiat currencies, the value of many cryptocurrencies is based on a fluctuating market with the currency exchanges publishing bid and ask prices per coin like a share of stock. Once worth a few cents, a single bitcoin jumped to thousands of dollars. Cryptocurrency traders hope to make fortunes with this phenomenon, which gathered immense steam in the 2010s. See stablecoin
