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.

Soon enough, however, ASICs were developed for Scrypt, and today it would be difficult if not impossible to turn a profit using anything but ASICs. One popular ASIC for Scrypt mining is Bitmain's Antminer L3+, but batches tend to sell out almost immediately, meaning you have to watch Twitter like a hawk; the company only accepts bitcoin cash and USD wire transfers (for some batches it only takes the former). Innosilicon is accepting pre-orders for a competitor, the A4+ LTCMaster. Other options are available, but the newest ASICs tend to run at least $2,000 and sell out quickly. Older ASICs may not be competitive, making it hard to turn a profit.расшифровка bitcoin bitcoin bonus bitcoin государство

Before the launch of the network, estimates ranged from between 15% to 20% annual percent return (APR) for early validators. As of Jan. 5, 2021, the APR for the average validator one month into network launch is between 11% to 12%, according to the beaconcha.in calculator.bitcoin chain

bitcoin mmgp dollar bitcoin bitcoin atm bitcoin картинки ethereum rig зарабатывать bitcoin up bitcoin With a deterministic wallet a single key can be used to generate an entire tree of key pairs. This single key serves as the root of the tree. The generated mnemonic sentence or word seed is simply a more human-readable way of expressing the key used as the root, as it can be algorithmically converted into the root private key. Those words, in that order, will always generate exactly the same root key. A word phrase could consist of 24 words like: begin friend black earth beauty praise pride refuse horror believe relief gospel end destroy champion build better awesome. That single root key is not replacing all other private keys, but rather is being used to generate them. All the addresses still have different private keys, but they can all be restored by that single root key. The private keys to every address it has and will ever give out in the future can be recalculated given the root key. That root key, in turn, can be recalculated by feeding in the word seed. The mnemonic sentence is the backup of the wallet. If a wallet supports the same (mnemonic sentence) technique, then the backup can also be restored on another software or hardware wallet.tether provisioning
