Common forms of Cryptocurrency

• Bitcoin
  Since Bitcoin was the first cryptocurrency, it continues to be the coin that comes to mind when talking about digital currency. According to its mysterious creator Satoshi Nakamoto, the currency made its debut in 2009 and has since gone on a roller-coaster of a trip.

• Ethereum
  In the realm of cryptocurrencies, Ethereum, the name of the platform, is the second term you're most likely to remember. The system's currency, ether, can be used for a variety of purposes, but Ethereum's smart contract feature increases its appeal.

• Tether
  Tether coins are sold with a fixed price of $1 each. This is as a result of it being a stablecoin. With Tether, a certain asset's value is correlated to the value of the stablecoin. Oftentimes, when traders switch between cryptocurrencies, Tether acts as a bridge.

• USD Coin
  The value of USD Coin, which is a stablecoin like Tether, is locked to the US dollar and shouldn't fluctuate. The currency's founders assert that it is backed by fully reserved assets or those with "equivalent fair worth," and that these assets are held in accounts with institutions under the supervision of the United States.

• Dodgecoin
  Dogecoin gets its name from an online meme that features a Shiba Inu dog and was first made as a joke following the run-up in Bitcoin. Dogecoin features unrestricted issuance, in contrast to many other digital currencies that cap the number of coins that can be produced. It can be used to send money or make payments.

• Polygon
  A cryptocurrency called Polygon scales up Ethereum and focuses on being available to folks who are building digital apps. It was founded in 2017 and went by the moniker Matic before changing to Polygon in 2021.
