What is cryptocurrency?

  • Cryptocurrency is a form of payment that can be exchanged online for goods and services. Many companies have issued their own currencies, often called tokens, and these can be traded specifically for the good or service that the company provides. Think of them as you would arcade tokens or casino chips. You’ll need to exchange real currency for the cryptocurrency to access the good or service. Learn more about this see Paraiba World.

    Cryptocurrencies work using a technology called blockchain. Blockchain is a decentralized technology spread across many computers that manages and records transactions. Part of the appeal of this technology is its security.

    How many cryptocurrencies are there? What are they worth?

    More than 10,000 different cryptocurrencies are traded publicly, according to CoinMarketCap.com, a market research website. And cryptocurrencies continue to proliferate, raising money through initial coin offerings, or ICOs. The total value of all cryptocurrencies on July 9, 2021, was more than $1.4 trillion — down from April high of $2.2 trillion, according to CoinMarketCap. The total value of all bitcoins, the most popular digital currency, was pegged at about $630 billion — down from April high of $1.2 trillion.

    Cryptocurrencies appeal to their supporters for a variety of reasons. Here are some of the most popular:

    • Supporters see cryptocurrencies such as Bitcoin as the currency of the future and are racing to buy them now, presumably before they become more valuable

    • Some supporters like the fact that cryptocurrency removes central banks from managing the money supply, since over time these banks tend to reduce the value of money via inflation

    • Other supporters like the technology behind cryptocurrencies, the blockchain, because it’s a decentralized processing and recording system and can be more secure than traditional payment systems

    • Some speculators like cryptocurrencies because they’re going up in value and have no interest in the currencies’ long-term acceptance as a way to move money
