Stablecoins
"Stable" is the key word here - this cryptocurrency differs from others as it is intends to be less volatile in value.

This typically works by the price being linked to an existing asset, for instance currencies like the US dollar or Pound Sterling, which in theory should make them more stable in price than cryptocurrencies that are not backed by assets.

Stablecoins themselves are usually controlled by companies that provide them, with transactions recorded on digital ledgers. While held up by some as the future of finance, high profile price collapses of stablecoins have alerted regulators to risks for investors and prompted scrutiny over their supposed stability.
