What is Stablecoin?

Stablecoins are cryptocurrencies whose value is pegged to stable (less volatile) financial assets, such as US Dollar, Euro, Gold, etc. for example –

1 USDT (Tether stablecoin) = 1 USD 

The company created stablecoin is responsible to maintain this peg.

Different Types of Stablecoins

There are two main categories of stablecoins.

Centralized Stablecoins

In general, centralized stablecoins backed by Fiat currencies or metals such as Gold. Companies issue new stablecoins and deposit the corresponding balance in banks which can be audited by any third-party auditors. 

Tether(USDT), USD Coin (USDC), Paxos are some of the examples of centralized stablecoins. 

With centralized stablecoins, you need to trust the company issuing these stablecoins to maintain transparency. 

Decentralized Stablecoins

Decentralized stablecoins such as DAI stablecoin manage these pegs using cryptocurrencies (ex- Ethereum) as collateral.

Dai stablecoin is implemented through smart contracts. Therefore anyone can audit these smart contracts to check issued stablecoins and collateral. In addition, decentralized stablecoins are permissionless systems without KYC or any kind of censorship.

In the case of decentralized stablecoin, there is two most important aspect of transparency. 

  • If the smart contract used to implement stablecoins are properly audited or not by an independent firm? so you can trust it with your assets.
  • Who owns the admin keys of stablecoin’s smart contracts, and are they used responsibly in the past.

Liquidity — Liquidity is one of the most important aspects whenever we talk about any financial asset. Without liquidity, you might not find buyers or sellers for your orders in the market. In addition, low liquidity coins are not widely integrated with third-party exchanges and businesses.

Stablecoin vs Bitcoin

Bitcoin and stablecoins are two very different assets because of their monetary policy and underlying blockchain. Bitcoin is not pegged to any fiat currency and has a limited supply. There will only be 21 million bitcoins ever. With Bitcoin monetary policy is coded in the software. Above all makes it a unique digital asset govern from its own crypto-economics, unaffected from the government’s monetary policy changes.

On the other hand, stablecoins are pegged to sovereign fiat currencies. The monetary policy of fiat currencies is governed by central banks and there is no limitation on supply. In addition, most of the stablecoins use blockchains like Etheruem, hence their security is directly dependent on Ethereum’s security.
