Cryptocurrency Definitions and Explanation – Digital currencies or cryptocurrencies are digital exchanges that can be created by individuals or groups.
Most cryptocurrencies are not regulated by national governments. They’re therefore considered alternative currencies, which is a form of financial exchange that exists outside of the boundaries of state monetary policy.
Bitcoin (BTC), is the most popular cryptocurrency and it was the first to be widely used. There are hundreds of other cryptocurrencies, and new ones appear every month.
Non-Bitcoin cryptocurrency are collectively called “altcoins” in order to differentiate them from the original.
Cryptocurrency Definitions and Explanation
Functionally, most cryptocurrency are variations of Bitcoin, the original widely-used cryptocurrency.
As traditional currencies, cryptocurrency also expresses value in units. You can say “I’ve 2.5 Bitcoin” just like you would say “I’ve $2.50.”
Because of their political independence, and almost impenetrable data security cryptocurrency users enjoy benefits that are not available to traditional fiat currencies such as the U.S. Dollar and the financial system that supports them.
A government may freeze or seize any bank account within its jurisdiction but it is very difficult to do so with cryptocurrency funds, even if the holder happens to be a citizen or legal resident.
However, cryptocurrencies have many drawbacks that aren’t experienced by fiat currencies.
Many countries also view cryptocurrencies with suspicion or outright animosity because they are often used to facilitate grey and black market transactions. Cryptocurrency Definitions and Explanation
While cryptocurrencies are touted as a potential investment option, very few financial professionals consider most coins to be suitable for any other purpose than pure speculation.
Tip: Are you hesitant about investing in crypto? allows you to dollar cost average your investment. You can set up montly or weekly investments, and you can even invest your spare money (just like Acorns).
How Cryptocurrencies Work
The source codes and technical controls necessary to secure and support cryptocurrencies are complex. But, even laypeople can understand the basics and become informed cryptocurrency users.
There are many concepts that govern cryptocurrency’s values, security, integrity.
Cryptocurrencies use cryptographic protocol, which is a highly complex code system that encrypts sensitive data transfers to protect their units of exchange.
These protocols are based on sophisticated mathematics and computer engineering principles, which make them nearly impossible to break and so they can be duplicated or copied.
These protocols also hide the identities of cryptocurrency users making it difficult to trace transactions or fund flows to particular individuals or groups.
Blockchain is the master public record that stores and records all transactions, activity and ownership.
A blockchain is the complete history of all cryptocurrency transactions to date. It has a finite length, which increases in time.
Every node in the cryptocurrency’s software networks stores identical copies of the blockchain — the network decentralized server farms that are run by computer-savvy people or groups known as miners and which continuously record and authenticate cryptocurrency transactions.
A cryptocurrency transaction is technically not finalized until it is added to the blockchain. This usually happens within minutes. It’s almost impossible to reverse a transaction once it is completed.
Most cryptocurrencies do not have built-in chargeback or refund functions like traditional payment processors such as PayPal or credit cards. However, some cryptocurrencies are starting to have basic refund capabilities.
The units can’t be used by either party during the time between transaction’s initiation or finalization. They are instead kept in an escrow, limbo for all intents. Cryptocurrency Definitions and Explanation
The blockchain prevents double-spending or manipulation of cryptocurrency code to allow currency units to be duplicated and then sent to multiple recipients.
The principle of decentralized control is an inherent feature of blockchain technology.
The supply and value of cryptocurrencies are determined by their users’ activities and the highly complex protocols that they have built into their governing codes. Not the conscious decisions made by central banks or other regulatory authorities.
Particularly, miners, cryptocurrency users who use large amounts of computing power and record transactions, receive newly created cryptocurrency units, and pay transaction fees to other users in return, are crucial to currency stability and smooth operation.
Each cryptocurrency holder is issued a private key, which authenticates their identity and allows them the ability to exchange units. You can either create your own private keys (which can be formatted as whole numbers of up to 78 digits or you can use a random number generator.
They can only obtain and spend cryptocurrency if they have the key. The key is required to convert or spend cryptocurrency. Cryptocurrency Definitions and Explanation
This is a crucial security feature that prevents theft and unauthorized usage, but it can also be very draconian. The digital equivalent of throwing money into a trash can is losing your private key.
You can create a new private key to start accumulating cryptocurrency again. However, the holdings that you have protected by your lost key cannot be recovered.
The most savvy cryptocurrency users are therefore extremely protective of their keys. They store them in multiple digital locations, although they are not usually connected to the Internet, and also on paper or in any other form.
Users of cryptocurrency have wallets that contain unique information that confirms they are the owners.
Private keys verify the authenticity of cryptocurrency transactions, but wallets reduce the risk of theft of units that aren’t being used.
Hacking is possible on cryptocurrency exchange wallets. Mt. Gox declared bankruptcy in 2009 after hackers forced it to pay $450 million in Bitcoins that had been transferred over its servers.
You can store your wallets on the cloud, on an internal hard drive or on an external storage device. No matter how your wallet is stored it is recommended to have at least one backup.
Not a duplicate of the actual cryptocurrency units. Backing up a wallet does not create a record of their existence.
The record-keepers of cryptocurrency communities and the indirect arbiters for currencies’ value, miners are important.
Miners use a lot of computing power to verify that currencies’ blockchains are complete, accurate, and secure.
The operation’s scope is similar to the search for new prime number, which requires enormous amounts of computing power.
The work of miners creates periodic copies of the blockchain and adds recent, unverified transactions to it. This completes those transactions.
A block is a collection of all additions. Blocks are all transactions that have been performed since the last copy of the blockchain was created.
The term “miners”, refers to the fact that miners create wealth literally in the form new cryptocurrency units. Cryptocurrency Definitions and Explanation
Each newly created blockchain copy is rewarded with two parts: a fixed number (“mined”) of cryptocurrency units and a variable amount of existing units from optional transaction fees, which are typically less than 1% of transaction value.
It is worth noting that cryptocurrency mining used to be a lucrative side-business for those who had the capital to invest in hardware-intensive and power-intensive mining operations.
Hobbyists today are unable to afford professional-grade mining equipment. Many freelance gigs can be a great way to supplement your regular income. Cryptocurrency Definitions and Explanation
Transaction fees are not charged to sellers. However, miners can prioritize fee-laden transactions over fee-free transactions in creating new blocks even though the fee-free transactions were first.
Sellers are more likely to charge transaction fees to make their sales faster. It’s quite common for transactions using cryptocurrency to be charged with fees.
While it is theoretically possible to make a new copy of a blockchain with previously unauthenticated transactions completely free of fees, this rarely happens in practice.
Cryptocurrencies automatically adjust to the amount mining power used to create new copies of blockchain. As mining power decreases, it becomes more difficult to create copies.
The goal is to maintain a predetermined interval between new blockchain creations. Bitcoin’s average interval is 10 minutes.
While mining can produce new cryptocurrency units periodically, most cryptocurrencies have a finite supply which is a key guarantor for value.
This means that miners will receive fewer units per block over time. Although this is unlikely to be the case in practice, miners may eventually only receive transaction fees.
If current trends continue to be followed, observers predict that Bitcoin’s last unit will be mined sometime around the middle of the 22nd century. This is not too far away. Cryptocurrency Definitions and Explanation
Because of their finite supply, cryptocurrencies are inherently deflationary. They are more like gold or other precious metals, which have finite supplies, than fiat currencies, which central banks can theoretically produce unlimited amounts of.
Some lesser-used cryptocurrency can only be exchanged via private, peer to-peer transfers. This means they are not liquid and difficult to value relative other currencies, both crypto-and fiat.
Ripple and Bitcoin are two of the most popular cryptocurrency, trading on special secondary Exchanges that are similar to forex exchanges for fiat currency. (The now-defunct Mt. One example of an exchange is Gox.
These platforms enable holders to trade their cryptocurrency holdings for fiat currencies such as the U.S. Dollar and Euro, and other cryptocurrencies.
They take a small percentage of the transaction’s value in return for their services. This is usually less than 1%.
Importantly, cryptocurrencies are able to be exchanged for fiat currencies on special online markets. Each currency has a variable exchange rate that is comparable with major currencies around the world, including the U.S. Dollar, British Pound, European Euro, and Japanese yen. Cryptocurrency Definitions and Explanation
The cryptocurrency exchanges play an important role in creating liquid markets and setting the value of popular cryptocurrencies relative to other currencies. Some crypto exchanges allow you to trade derivatives of cryptocurrency or track large-based cryptocurrency portfolios using crypto indexes.
But exchange pricing is still highly volatile. In the aftermath of Mt. Gox’s collapse was followed by a tenfold increase in 2017 due to increased cryptocurrency demand.
Cryptocurrency exchanges are vulnerable to hacking. They are the most popular venue for digital currency theft by hackers, and cybercriminals such as those responsible for taking down Mt. Gox.
