What to Know About Cryptocurrency

Cryptocurrency is digital money. That means there’s no physical coin or bill — it’s all online. You can transfer cryptocurrency to someone online without a go-between, like a bank. Bitcoin and Ether are well-known cryptocurrencies, but new cryptocurrencies continue to be created.
People might use cryptocurrencies for quick payments and to avoid transaction fees. Some might get cryptocurrencies as an investment, hoping the value goes up. You can buy cryptocurrency with a credit card or, in some cases, get it through a process called “mining.” Cryptocurrency is stored in a digital wallet, either online, on your computer, or on other hardware.
Before you buy cryptocurrency, know that it does not have the same protections as when you are using U.S. dollars. Also know that scammers are asking people to pay with cryptocurrency because they know that such payments are typically not reversible.

Cryptocurrencies vs. U.S. Dollars
The fact that cryptocurrencies are digital is not the only important difference between cryptocurrencies and traditional currencies like U.S. dollars.
Cryptocurrencies aren’t backed by a government.
Cryptocurrencies are not insured by the government like U.S. bank deposits are. This means that cryptocurrency stored online does not have the same protections as money in a bank account. If you store your cryptocurrency in a digital wallet provided by a company, and the company goes out of business or is hacked, the government may not be able to step and help get your money back as it would with money stored in banks or credit unions.
A cryptocurrency’s value changes constantly.
A cryptocurrency’s value can change by the hour. An investment that may be worth thousands of U.S. dollars today might be worth only hundreds tomorrow. If the value goes down, there’s no guarantee that it will go up again.
Investing in Cryptocurrency
As with any investment, before you invest in cryptocurrency, know the risks and how to spot a scam. Here are some things to watch out for as you consider your options.
No one can guarantee you’ll make money.
Anyone who promises you a guaranteed return or profit is likely a scammer. Just because an investment is well known or has celebrity endorsements does not mean it is good or safe. That holds true for cryptocurrency, just as it does for more traditional investments. Don’t invest money you can’t afford to lose.
Not all cryptocurrencies — or companies promoting cryptocurrency — are the same.
Look into the claims that companies promoting cryptocurrency are making. Search online for the name of the company, the cryptocurrency name, plus words like “review,” “scam,” or “complaint.”

Paying with Cryptocurrency
If you are thinking about using cryptocurrency to make a payment, know the important differences between paying with cryptocurrency and paying by traditional methods.
You don’t have the same legal protections when you pay with cryptocurrency.
Credit cards and debit cards have legal protections if something goes wrong. For example, if you need to dispute a purchase, your credit card company has a process to help you get your money back. Cryptocurrency payments typically are not reversible. Once you pay with cryptocurrency, you only can get your money back if the seller sends it back.
Before you buy something with cryptocurrency, know a seller’s reputation, where the seller is located, and how to contact someone if there is a problem.
Refunds might not be in cryptocurrency.
If refunds are offered, find out whether they will be in cryptocurrency, U.S. dollars, or something else. And how much will your refund be? The value of a cryptocurrency changes constantly. Before you buy something with cryptocurrency, learn how the seller calculates refunds.
Some information will likely be public.
Although cryptocurrency transactions are anonymous, the transactions may be posted to a public ledger, like Bitcoin’s blockchain. A blockchain is a public list of records that shows when someone transacts with cryptocurrency. Depending on the cryptocurrency, the information added to the blockchain can include information like the transaction amount. The information also can include the sender’s and recipient’s wallet addresses — a long string of numbers and letters linked to a digital wallet that stores cryptocurrency. Both the transaction amount and wallet addresses could be used to identify who the actual people using it are.
Cryptocurrency Scams
As more people get interested in cryptocurrency, scammers are finding more ways to use it. For example, scammers might offer investment and business “opportunities,” promising to double your investment or give you financial freedom.
Watch out for anyone who:
guarantees that you’ll make money
promises big payouts that will double your money in a short time
promises free money in dollars or cryptocurrency
makes claims about their company that are not clear
Cryptojacking
Cryptojacking is when scammers use your computer or smartphone’s processing power to “mine” cryptocurrency for their own benefit, and without your permission. Scammers can put malicious code onto your device simply by your visiting a website. Then they can help themselves to your device’s processor without you knowing.
If you notice that your device is slower than usual, burns through battery power quickly, or crashes, your device might have been cryptojacked. Here is what to do about it:
Close sites or apps that slow your device or drain your battery.
Use antivirus software, set software and apps to update automatically, and never install software or apps you do not trust.
Do not click links without knowing where they lead, and be careful about visiting unfamiliar websites.
Consider a browser extension or ad blockers that can help defend against cryptojacking. But do your research first. Read reviews and check trusted sources before installing any online tools. Some websites may keep you from using their site if you have blocking software installed.

The Bitcoin blockchain is a database (known as a 'ledger') that consists only of Bitcoin transaction records. There is no central location that holds the database, instead, it is shared across a huge network of computers. So, for new transactions to be added to the database, the nodes must agree that the transaction is real and valid.proposal is under-specified (omitting all the possible race conditions and de-synchronization attacks and scenarios in a distributed system) and details available only in ad hoc code21bitcoin gold bitcoin значок криптовалют ethereum bitcoin check ethereum vk bitcoin рублях ethereum pool cryptocurrency dash boom bitcoin dwarfpool monero робот bitcoin вирус bitcoin 99 bitcoin rate bitcoin ethereum ico nonce bitcoin bitcoin приложение Tweetreverse tether

What is Cold Storage?bitcoin проект Bitcoin exchanges such as Coinbase bring together market participants from around the world to buy and sell cryptocurrencies. These exchanges have been both increasingly popular (as Bitcoin's popularity itself has grown in recent years) and fraught with regulatory, legal and security challenges. With governments around the world viewing cryptocurrencies in various ways – as currency, as an asset class, or any number of other classifications – the regulations governing the buying and selling of bitcoins are complex and constantly shifting. Perhaps even more important for Bitcoin exchange participants than the threat of changing regulatory oversight, however, is that of theft and other criminal activity. While the Bitcoin network itself has largely been secure throughout its history, individual exchanges are not necessarily the same. Many thefts have targeted high-profile cryptocurrency exchanges, oftentimes resulting in the loss of millions of dollars worth of tokens. The most famous exchange theft is likely Mt. Gox, which dominated the Bitcoin transaction space up through 2014. Early in that year, the platform announced the probable theft of roughly 850,000 BTC worth close to $450 million at the time. Mt. Gox filed for bankruptcy and shuttered its doors; to this day, the majority of that stolen bounty (which would now be worth a total of about $8 billion) has not been recovered.Bangladeshexchange cryptocurrency bitcoin hd People are always under the threat of having their identities stolen by cyber-thieves — also known as hackers.

ethereum вики It may be the case at some point that it will become desirable to render some UTXOs unspendable in order to protect the network, such as P2PK funds that could be vulnerable to quantum attacks.
