Cryptocurrencies were originally envisioned as a decentralized payment means, independent of fiat money rates and not tied to traditional valuable assets.
This peculiarity adds cryptocurrencies a characteristic feature — high volatility of the rate. Many folks gain thanks to this feature, but the possibility that the rate can dramatically drop or leap hinders the usage of cryptocurrency as a full-fledge payment means.
In order to regulate the rate, it was decided to tie up cryptocurrencies to stable assets that have long been established in the economy. Thus, they began to tie up the value of cryptocurrency to fiat money, gold and oil. Digital currencies can be tied up to any valuable asset or commodity which can make their value more stable.
Cryptocurrencies pegged to physical assets have a lower rate volatility and became known as stablecoins. Stablecoins are a compromise between fiat money and cryptocurrencies. Most often, the value of a stablecoin is pegged to fiat money. The value of these coins is equal to that of fiat currency and represents a sort of a promissory note. Every coin is leveraged to one unit of fiat money, for instance, dollar, which acts as a guarantee and provides for the value of the currency.
The most popular stablecoins are:
Tether (USDT) * USD Coin (USDC) * TrueUSD (TUSD) * Paxos Standard Token (PAX) * Dai (DAI)
And what stablecoins do you use?
