Cryptocurrency Exchange
A cryptocurrency exchange, or a digital currency exchange (DCE), is a business that allows customers to trade cryptocurrencies or digital currencies for other assets, such as conventional fiat money or other digital currencies. Exchanges may accept credit card payments, wire transfers or other forms of payment in exchange for digital currencies or cryptocurrencies. A cryptocurrency exchange can be a market maker that typically takes the bid–ask spreads as a transaction commission for its service or, as a matching platform, simply charges fees. Some brokerages which also focus on other assets such as stocks, let users purchase but not withdraw cryptocurrencies to cryptocurrency wallets while dedicated cryptocurrency exchanges do allow cryptocurrency withdrawals. Operation A cryptocurrency exchange can typically send cryptocurrency to a user's personal cryptocurrency wallet.

Ethereum Classic
Ethereum Classic is a blockchain-based distributed computing platform that offers smart contract (scripting) functionality. It is open source and supports a modified version of Nakamoto consensus via transaction-based state transitions executed on a public Ethereum Virtual Machine (EVM). Ethereum Classic maintains the original, unaltered history of the Ethereum network. The Ethereum project's mainnet was initially released via Frontier on 30 July 2015. However, due to a hack of a third-party project, The DAO, the Ethereum Foundation created a new version of the Ethereum mainnet on 20 July 2016 with an ''irregular state change'' implemented that erased the DAO theft from the Ethereum blockchain history. The Ethereum Foundation applied their trademark to the new, altered version of the Ethereum blockchain. The older, unaltered version of Ethereum was renamed and continued on as Ethereum Classic. Ethereum Classic's native Ether token is a cryptocurrency traded on digital curre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Insurance Broker

Insurance In The United States
Insurance in the United States refers to the market for risk in the United States, the world's largest insurance market by premium volume. According to Swiss Re, of the $7.186 trillion of global direct premiums written worldwide in 2023, $3.226 trillion (44.9%) were written in the United States. Insurance, generally, is a contract in which the insurer agrees to compensate or indemnify another party (the insured, the policyholder or a beneficiary) for specified loss or damage to a specified thing (e.g., an item, property or life) from certain perils or risks in exchange for a fee (the insurance premium). For example, a property insurance company may agree to bear the risk that a particular piece of property (e.g., a car or a house) may suffer a specific type or types of damage or loss during a certain period of time in exchange for a fee from the policyholder who would otherwise be responsible for that damage or loss. That agreement takes the form of an insurance policy. His ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Dollar
The United States dollar (Currency symbol, symbol: Dollar sign, $; ISO 4217, currency code: USD) is the official currency of the United States and International use of the U.S. dollar, several other countries. The Coinage Act of 1792 introduced the U.S. dollar at par with the Spanish dollar, Spanish silver dollar, divided it into 100 cent (currency), cents, and authorized the Mint (facility), minting of coins denominated in dollars and cents. U.S. banknotes are issued in the form of Federal Reserve Notes, popularly called greenbacks due to their predominantly green color. The U.S. dollar was originally defined under a bimetallism, bimetallic standard of (0.7734375 troy ounces) fine silver or, from Coinage Act of 1834, 1834, fine gold, or $20.67 per troy ounce.

Currency Peg
A fixed exchange rate, often called a pegged exchange rate, is a type of exchange rate regime in which a currency's value is fixed or pegged by a monetary authority against the value of another currency, a basket of other currencies, or another measure of value, such as gold or silver. There are benefits and risks to using a fixed exchange rate system. A fixed exchange rate is typically used to stabilize the exchange rate of a currency by directly fixing its value in a predetermined ratio to a different, more stable, or more internationally prevalent currency (or currencies) to which the currency is pegged. In doing so, the exchange rate between the currency and its peg does not change based on market conditions, unlike in a floating (flexible) exchange regime. This makes trade and investments between the two currency areas easier and more predictable and is especially useful for small economies that borrow primarily in foreign currency and in which external trade forms a large ...

Stablecoin
A stablecoin is a type of cryptocurrency where the value of the digital asset is supposed to be pegged to a reference asset, which is either fiat money, exchange-traded commodities (such as precious metals or industrial metals), or another cryptocurrency. In theory, 1:1 backing by a reference asset could make a stablecoin value track the value of the peg and not be subject to the radical changes in value common in the market for many digital assets. In practice, stablecoin issuers have yet to be proven to maintain adequate reserves to support a stable value, and there have been a number of failures with investors losing the entirety of the (fiat currency) value of their holdings. Background Stablecoins have several purported purposes. They can be used for payments and are more likely to retain value than highly volatile cryptocurrencies. In practice, many stablecoins have failed to retain their "stable" value. Stablecoins are typically non-interest bearing and therefore do no ...

Cryptocurrency
A cryptocurrency (colloquially crypto) is a digital currency designed to work through a computer network that is not reliant on any central authority, such as a government or bank, to uphold or maintain it. Individual coin ownership records are stored in a digital ledger or blockchain, which is a computerized database that uses a consensus mechanism to secure transaction records, control the creation of additional coins, and verify the transfer of coin ownership. The two most common consensus mechanisms are proof of work and proof of stake. Despite the name, which has come to describe many of the fungible blockchain tokens that have been created, cryptocurrencies are not considered to be currencies in the traditional sense, and varying legal treatments have been applied to them in various jurisdictions, including classification as commodities, securities, and currencies. Cryptocurrencies are generally viewed as a distinct asset class in practice. The first cryptocu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zcash
Zcash is a privacy-focused cryptocurrency based on Bitcoin's codebase. It shares many similarities, such as a fixed total supply of 21 million units. Transactions can be transparent, similar to bitcoin transactions, or they can be shielded transactions which use a type of zero-knowledge proof to provide anonymity in transactions. Zcash coins are either in a transparent pool or a shielded pool. Zcash offers private transactors the option of "selective disclosure," allowing users to prove payment for auditing purposes. One such reason is to make it easier for private transactors to comply with anti-money laundering laws and tax regulations. Use Zcash transactions can be transparent, similar to bitcoin transactions, in which case they are controlled by a "t-addr" or shielded and controlled by a "z-addr." A shielded transaction uses a type of zero-knowledge proof, specifically a non-interactive zero-knowledge proof, called "zk-SNARK," which provides anonymity to the coin hold ...

Futures Contract
In finance, a futures contract (sometimes called futures) is a standardized legal contract to buy or sell something at a predetermined price for delivery at a specified time in the future, between parties not yet known to each other. The item transacted is usually a commodity or financial instrument. The predetermined price of the contract is known as the ''forward price'' or ''delivery price''. The specified time in the future when delivery and payment occur is known as the ''delivery date''. Because it derives its value from the value of the underlying asset, a futures contract is a Derivative (finance), derivative. Contracts are traded at futures exchanges, which act as a marketplace between buyers and sellers. The buyer of a contract is said to be the Long (finance), long position holder and the selling party is said to be the Short (finance), short position holder.
