What is the Main Purpose of Cryptocurrency?

The primary goal of cryptocurrency is to address the issues of traditional currencies by placing power and responsibility in the hands of currency holders. All cryptocurrencies adhere to the 5 properties and 3 functions of money, while also attempting to solve one or more real-world problems. Cryptocurrency is a digital or virtual currency that is secured by cryptography, making it almost impossible to counterfeit or double-spend. Many cryptocurrencies are decentralized networks based on blockchain technology, a distributed ledger enforced by a disparate network of computers.

A defining characteristic of cryptocurrencies is that they are generally not issued by any central authority, which makes them theoretically immune to government interference or manipulation. Cryptocurrency is decentralized digital money that is based on blockchain technology. Bitcoin and Ethereum are the most popular versions, but there are more than 19,000 different cryptocurrencies in circulation. A cryptocurrency is a digital, encrypted and decentralized medium of exchange.

Unlike the Dollar or Euro, there is no central authority that manages and maintains the value of a cryptocurrency. Instead, these tasks are widely distributed among users of a cryptocurrency over the Internet. You can use cryptocurrencies to buy regular goods and services, although most people invest in cryptocurrencies as they would in other assets, such as stocks or precious metals. While cryptocurrency is a novel and exciting asset class, buying it can be risky, as you need to do a lot of research to understand how each system works.

That cryptographic proof comes in the form of transactions that are verified and recorded on a blockchain. A blockchain is an open, distributed ledger that records transactions in code. In practice, it looks a bit like a checkbook that is distributed on countless computers around the world. Transactions are recorded in “blocks” that are then linked in a “chain” of previous cryptocurrency transactions.

With a blockchain, everyone using a cryptocurrency has their own copy of this ledger to create a unified transaction log. Every new transaction as it occurs is recorded and every copy of the blockchain is updated simultaneously with the new information, keeping all records identical and accurate. To prevent fraud, each transaction is verified using a validation technique, such as proof of work or proof of stake. Proof of Work and Proof of Stake are the two most commonly used consensus mechanisms for verifying transactions before adding them to a blockchain.

Verifiers are rewarded with cryptocurrency for their efforts. The race to solve blockchain puzzles can require a lot of energy and electricity. That means miners may barely break even with the cryptocurrencies they receive to validate transactions after considering energy and computing resource costs. Some cryptocurrencies use a proof-of-stake verification method to reduce the amount of energy needed to verify transactions.

With proof of stake, the number of transactions each person can verify is limited by the amount of cryptocurrency they are willing to “bet”, or is temporarily kept in a community safe for an opportunity to participate in the process. Ethereum estimates its energy use will decline by 99.95% once it closes “The Last Chapter of the Proof of Work on Ethereum”. Both proof of stake and proof of work rely on consensus mechanisms to verify transactions. This means that, while each uses individual users to verify transactions, each verified transaction must be verified and approved by most ledger holders.

Mining is the way in which new units of cryptocurrency are released to the world, usually in exchange for validating transactions. While it's theoretically possible for the average person to mine cryptocurrencies, it's increasingly difficult in proof-of-work systems, such as Bitcoin. Proof-of-Work Cryptocurrencies also require huge amounts of energy to mine; for example, Bitcoin mining currently consumes electricity at an annualized rate of 127 terawatt-hours (TWh), which exceeds all annual electricity consumption in Norway. Using cryptocurrency to make secure purchases depends on what you're trying to buy.

If you're trying to make a cryptocurrency payment, you'll most likely need a cryptocurrency wallet; one type of wallet is a “hot wallet”, a software program that interacts with the blockchain and allows users to send and receive their stored cryptocurrency. Remember that transactions are not instantaneous since they must be validated by some type of mechanism. Cryptocurrencies can be purchased through cryptocurrency exchanges such as Coinbase, Kraken or Gemini; they offer the ability to trade some of the most popular cryptocurrencies such as Bitcoin, Ethereum and Dogecoin but can also have limitations; you'll need to check if your exchange supports the correct crypto pairing you need to make a purchase; for example you can use your stash of USD Coin (a stable cryptocurrency) to buy Ethereum on Coinbase Exchange but keep an eye out for fees as some exchanges charge prohibitively high costs on small cryptocurrency purchases; we've reviewed top exchange offerings and heaps of data to determine best cryptocurrency exchanges. Some brokerage platforms such as Robinhood, Webull and eToro allow you to invest in cryptocurrencies; that's in addition to cryptocurrency exchanges; it's best to keep in mind that buying individual cryptocurrencies is similar to buying individual stocks.
