1. 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.
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.

3. Why are cryptocurrencies so popular?
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

4. Are cryptocurrencies a good investment?
Cryptocurrencies may go up in value, but many investors see them as mere speculations, not real investments. The reason? Just like real currencies, cryptocurrencies generate no cash flow, so for you to profit, someone has to pay more for the currency than you did.
That’s what’s called “the greater fool” theory of investment. Contrast that to a well-managed business, which increases its value over time by growing the profitability and cash flow of the operation.
“
For those who see cryptocurrencies such as bitcoin as the currency of the future, it should be noted that a currency needs stability.”
As NerdWallet writers have noted, cryptocurrencies such as Bitcoin may not be that safe, and some notable voices in the investment community have advised would-be investors to steer clear of them. Of particular note, legendary investor Warren Buffett compared Bitcoin to paper checks: “It's a very effective way of transmitting money and you can do it anonymously and all that. A check is a way of transmitting money too. Are checks worth a whole lot of money? Just because they can transmit money?"
For those who see cryptocurrencies such as Bitcoin as the currency of the future, it should be noted that a currency needs stability so that merchants and consumers can determine what a fair price is for goods. Bitcoin and other cryptocurrencies have been anything but stable through much of their history. For example, while Bitcoin traded at close to $20,000 in December 2017, its value then dropped to as low as about $3,200 a year later. By December 2020, it was trading at record levels again.
This price volatility creates a conundrum. If bitcoins might be worth a lot more in the future, people are less likely to spend and circulate them today, making them less viable as a currency. Why spend a bitcoin when it could be worth three times the value next year?

As a result, Bitcoin’s 'halving' events, in which the emission rate of Bitcoin paid to miners is reduced automatically by the network in periodic intervals, produce price appreciation as well. Accumulation has held relatively constant for 9 years, but volatility is characteristic, and it is unknown how the market will react once the emission period has ended and all 21 million bitcoin are in circulation.

Bitcoin is a decentralized digital currency, without a central bank or single administrator that can be sent from user to user on the peer-to-peer bitcoin network without the need for intermediaries. Transactions are verified by network nodes through cryptography and recorded in a public distributed ledger called a blockchain. Bitcoins are created as a reward for a process known as mining. They can be exchanged for other currencies, products, and services. Research produced by the University of Cambridge estimated that in 2017, there were 2.9 to 5.8 million unique users using a cryptocurrency wallet, most of them using bitcoin.New Hampshire requires bitcoin sellers to get a money transmitter license and post a $100,000 bond. In Texas, the state securities commission is monitoring (and, on occasion, shutting down) bitcoin-related investment opportunities. And California is in bitcoin regulation limbo after freezing progress on Bill 1326 which – while criticized for issues such as overly broad definitions – was seen as less oppressive than New York’s BitLicense.ethereum цена

Blockchain. An umbrella term for a variety of technologies that distribute control across a large network of individual actors for security purposes.Bitcoin is a singular form of digital money where users can send, receive, and hold only bitcoins. Ethereum is a smart contract platform which allows entities to leverage blockchain technology to create numerous different digital ledgers and can be used to create additional cryptocurrencies that run on top of its blockchain. For example, Ethereum can be used to create tokens that are pegged 1:1 with the value of the United States dollar (called a stablecoin) if a user wanted to transfer or hold the value of dollars on the blockchain. Ether itself can also be sent, received and held as digital money.bitcoin obmen byzantium ethereum monero майнить bitcoin 100 dorks bitcoin forum ethereum tether gps eobot bitcoin
