Cryptocurrency is also known as digital currency. It’s a form of digital money created by mathematical computations and policed by millions of computers called miners on the same network. Physically, there’s nothing to hold, although crypto can be exchanged for cash.
Crypto comes from the word cryptographywhich is the process used to protect the transactions that send the lines of code for purchases. Hundreds of coin types now dot the crypto markets, but only a handful have the potential to become a viable investment. Governments have no control over the creation of cryptocurrencies, which is what initially made them so popular. Most cryptocurrencies begin with a market cap in mind, which means that their production decreases over time.
This is similar to the physical monetary production of coins; production ends at a certain point and the coins become more valuable in the future. No one knows who created it — most cryptocurrencies are designed for maximum anonymity — but bitcoins first appeared in from a developer reportedly named Satoshi Nakamoto. He has since disappeared and left behind a bitcoin fortune.
Because bitcoin was the first major cryptocurrency, all digital currencies created since then are called altcoins, or alternative coins. LitecoinPeercoinFeathercoinEthereumand hundreds of other coins are all altcoins because they are not bitcoin.
One of the advantages of bitcoin is that it can be stored offline on local hardware, such as a secure hard drive. This process is called cold storage, and it protects the currency from being stolen by. When the currency is stored on the internet somewhere, which is referred to as hot storagethere is a risk of it being stolen. On the flip side, if a person loses access to the hardware that contains the bitcoins, the currency is gone forever.

Bitcoins and altcoins are controversial because they take the power of issuing money away from central banks and give it to the general public. Bitcoin accounts cannot be frozen or examined by tax inspectors, and middleman banks are unnecessary for bitcoins to.
Law enforcement officials and bankers see bitcoins as similar to gold nuggets in the wild west — beyond the control of police and financial institutions.
Once bitcoins are owned by a person, they behave like physical gold coins. They possess value and trade just as if they were nuggets of gold. Bitcoins can be used to purchase goods and services online with businesses that accept them or can be tucked away in the hope that their value increases over time.
Bitcoins are traded from one personal wallet to. A wallet is a small personal database that is stored on a computer drive, smartphonetablet, or in the cloud. Bitcoins are forgery-resistant because multiple computers, called nodes, on the network must confirm the validity of every transaction.
It is so computationally intensive to create a bitcoin that it isn’t financially worth it for counterfeiters to manipulate the. A single bitcoin varies in value daily.

Bitcoins are stewarded by miners, the network of people who contribute their personal computer resources to the bitcoin network. Miners act as ledger keepers and auditors for all bitcoin transactions. Miners are paid for their accounting work by earning new bitcoins for the amount of resources they contribute to the network.
Each blockchain is unique to each user and the user’s personal bitcoin wallet. All bitcoin transactions are logged and made available in a public ledger, which ensures their authenticity and prevents fraud. This process prevents transactions from being duplicated and people from copying bitcoins. While every bitcoin records the digital address of every wallet it touches, the bitcoin system does not record the names of the people who own wallets.
In practical terms, this means that every bitcoin transaction is digitally confirmed but is completely anonymous at the same time. So, although people cannot easily see the personal identity or the details of the transaction, they can see the verified financial history of a bitcoin wallet.
This is a good thing, as a public history adds transparency and security to every transaction. Bitcoin mining involves commanding a home computer to work around the clock to solve proof-of-work problems computationally intensive math problems.

A single personal computer that mines bitcoins may earn 50 cents to 75 cents per day, minus electricity costs. Bitcoin mining is profitable only for those who run multiple computers with high-performance video processing cards and who join a group of miners to combine hardware power.

During these few seconds, a dishonest person who employs fast clicking can submit a second payment of the same bitcoins to a different recipient.
