Glossary Term: Cryptocurrency

In the context of cryptocurrencies, “decentralized” refers to the distributed nature of the network that underpins blockchain technology, which is the foundational technology of most cryptocurrencies.

Traditionally, financial transactions have been managed and controlled by central authorities such as banks or governments. These centralized systems maintain the ledger of transactions and are responsible for verifying and recording new transactions.

Decentralized systems, on the other hand, distribute the ledger (the record of transactions) across many nodes or participants in the network. This means that no single entity has complete control over the entire network. Transactions in a decentralized network are verified by a consensus mechanism among the network’s nodes, rather than by a central authority.

The advantages of decentralization include:

1. Security and Trust: Because the ledger is distributed across many nodes, it’s very difficult for a malicious actor to manipulate the transaction data. Each node has a copy of the entire ledger, and any changes would need to be accepted by a majority of nodes.
2. Transparency: All transactions are recorded on the blockchain and are publicly viewable. This increases transparency and makes it more difficult for fraudulent activities to occur.
3. Permissionless and Censorship Resistant: Anyone can participate in a decentralized network, and because no single entity controls it, it’s difficult to censor or control.
4. Disintermediation: Removes intermediaries from transactions which can lead to increased efficiency and reduced costs.

However, there are also challenges to decentralization, such as potential scalability issues, the technological learning curve for users, and regulatory hurdles. Despite these challenges, the idea of decentralization is a core tenet of many cryptocurrencies and blockchain-based systems.

In the context of cryptocurrencies, “centralized” refers to a system or network structure where control is maintained by a single authority, such as a centralized bank in traditional finance. This contrasts with decentralized networks, which are a defining characteristic of many cryptocurrencies, such as Bitcoin.

In a centralized system:

1. A single authority (like a bank or government) has control over all transactions.
2. Transactions go through this central authority, which can verify them and keep records.
3. This authority has the ability to regulate, censor, or reverse transactions.

In the world of cryptocurrencies, examples of centralized systems would be centralized exchanges (CEX), like Coinbase or Binance, where transactions are controlled and verified by the organization running the exchange.

Centralized systems also exist in crypto in the form of certain types of digital currencies. Some cryptocurrencies, particularly those issued by states (known as CBDCs, or Central Bank Digital Currencies), corporations, or private organizations, can be centralized, as they are issued and regulated by a single entity. The management can regulate the supply of currency, validate transactions, and may even have control over who can use the currency.

While centralized systems have some benefits, like speed and efficiency of transactions, they also have drawbacks, such as vulnerability to hacking, and the potential for censorship or misuse of power by the central authority. The concept of decentralization in cryptocurrencies was initially proposed to mitigate these issues.

A market maker in financial markets is an individual or institution that quotes both a buy and a sell price in a financial instrument or commodity, with the intention of making a profit on the bid-offer spread, or turn. They essentially create a market for the financial instrument by always standing ready to buy or sell.

Market makers play a critical role in ensuring liquidity in financial markets. Without market makers, there would be fewer transactions and less liquidity, which could lead to larger spreads between the bid and ask prices, resulting in higher costs for traders and investors.

Examples of market makers include large banks and brokerage firms. For instance, in the equities markets, they might buy stocks and hold them in their accounts in anticipation of selling these shares to other traders or investors. In the foreign exchange markets, market makers might take the opposite side of a trader’s transaction to ensure they can execute the trade at the desired price.

In essence, market makers act as wholesalers in the financial markets, buying and selling financial instruments to meet the demand from retail traders and investors. They help to ensure that trading can occur smoothly and efficiently, and they take on a significant amount of risk to provide this service.

In the world of trading, a market taker is someone who accepts the current market price of a financial instrument. Essentially, they ‘take’ the prices that ‘makers’ set.

Here’s a little more context:

1. Market Order: Market takers usually execute market orders. A market order is a type of order to buy or sell a security immediately at the best available current price.
2. Liquidity: Market takers contribute to the liquidity of the market. Liquidity refers to how quickly and easily a security can be bought or sold without significantly affecting the security’s price.
3. Market Makers vs Market Takers: This contrasts with market makers, who provide liquidity to the market by placing limit orders on the order book, effectively ‘making’ the market. Market takers, on the other hand, consume the liquidity by placing orders that get filled immediately against an existing order on the order book.
4. Fees: Exchanges often charge different fees for market makers and market takers. Market takers typically pay a higher fee because they are consuming the market’s liquidity, while market makers are often incentivized with lower fees or even rebates, as they contribute to the market’s liquidity.

In conclusion, a market taker is a trader who buys or sells securities at the current market price, which is determined by the standing limit orders on the exchange’s order book.

“Burning” in the context of cryptocurrency is the process of permanently removing coins or tokens from circulation, effectively reducing the total supply available.

This process is typically accomplished by sending a portion of the tokens to a designated “burn address”—a public address with no known private key. Without a private key, it’s impossible to access or use the tokens sent to the burn address. Hence, they’re effectively removed from circulation, considered “burned.”

Burning can serve a few different purposes in cryptocurrency systems:

1. To manage inflation: By reducing the total supply of tokens, burning can increase the relative value of each remaining token, assuming demand stays constant or increases.
2. To reward holders: Sometimes, projects will burn tokens to increase the value of the remaining tokens, indirectly rewarding those who hold the token.
3. To destroy unsold tokens: After an Initial Coin Offering (ICO) or a token sale, any unsold tokens might be burned to avoid flooding the market.
4. Tokenomics model: Some cryptocurrencies, like Binance Coin (BNB), have a model where a portion of tokens gets burned periodically.
5. Proof of Burn: Some coins use a mechanism called “Proof of Burn,” where miners must show proof that they’ve burned some coins by sending them to a non-retrievable address to create a new block in the blockchain.
6. To pay for transaction fees or other operations: On some platforms, tokens are burned as a means of paying for certain operations, like executing smart contracts.

Remember that the specific implications and purposes of burning can vary widely between different cryptocurrencies, as each can have its own unique rules and systems.

“Average down” is an investment strategy where an investor buys more shares of a stock as the price goes down. This has the effect of lowering the average price that the investor paid for the shares.

For instance, let’s say an investor buys 100 shares of a company at $10 each. If the price drops to $5, the investor might buy an additional 100 shares. The average cost of the shares is now $7.50, even though the current price is only $5.

The strategy is often used by investors who believe that the price drop is temporary and that the price will eventually rebound. By averaging down, they aim to benefit more from the rebound because they own more shares at a lower average cost.

However, it’s also a strategy that carries considerable risk. If the stock’s price continues to fall or never rebounds, the investor stands to lose more money. In other words, it can lead to “throwing good money after bad.” Therefore, it’s critical to apply this strategy in the context of a well-reasoned belief in the stock’s long-term potential.

In trading and investing, “short” or “short selling” is a strategy where an investor borrows a stock or another asset from a broker and sells it immediately at its current price. Then, the investor aims to repurchase the stock or asset later at a lower price, return it to the broker, and pocket the difference.

Here’s a step-by-step explanation of the process:

1. An investor anticipates that the price of a particular stock will drop.
2. They borrow shares of that stock from a broker, then sell those borrowed shares at the current market price.
3. If the price of the stock does drop as the investor anticipated, they can buy back the same number of shares at the lower price.
4. The investor then returns the shares to the broker, keeping the difference between the selling price and the repurchase price as profit.

If the stock’s price rises, however, the investor will have to buy it back at a higher price, and they’ll lose money. Because of this, short selling can be a risky strategy. In theory, potential losses are unlimited because a stock’s price could continue rising indefinitely.

It’s also important to know that brokers can charge fees for lending the stock, and these costs can reduce the profit from short selling or increase losses.

This practice is common in stock and futures markets. However, it can be controversial because it can potentially exacerbate market declines.

Capital gain refers to the increase in value of an asset or investment – it is essentially the profit that you realize when you sell an asset for more than you purchased it for.

In trading, this is usually applied to investments such as stocks, bonds, real estate, or any other form of securities. For example, if you bought a stock for $10 and sold it for $20, you’d have a capital gain of $10.

There are two types of capital gains: short-term and long-term.

1. Short-term capital gains are usually applied to assets held for less than a year before being sold. These are typically taxed at a higher rate because they’re considered as ordinary income.
2. Long-term capital gains apply to assets held for more than a year before being sold. The tax rates for long-term capital gains are generally lower than short-term gains, which is designed to encourage long-term investing.

Note that capital gains are not realized until the asset is sold. If your stock increased in value, but you have not yet sold it, this is considered an unrealized capital gain. You only owe taxes on capital gains once they are realized.

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.

Bitcoin was invented in 2008 by an unknown person or group of people using the name Satoshi Nakamoto. The currency began use in 2009 when its implementation was released as open-source software.

Bitcoin transactions are more secure than traditional financial transactions because they do not rely on trust in a specific counterparty. The blockchain ledger is transparent, meaning anyone can view the transaction history. However, the identities of the parties involved in each transaction are encrypted, providing a level of privacy and anonymity.

Bitcoins are created as a reward for a process known as mining. They can be exchanged for other currencies, products, and services, but the exchange rate is highly volatile. Bitcoin has faced criticism for its association with illegal transactions, its high electricity consumption, and potential for facilitating money laundering and tax evasion. Despite this, it has also been lauded for its potential to bypass traditional financial intermediaries, and it has spawned a multitude of other cryptocurrencies and blockchain-based technologies.

A candlestick chart is a style of financial chart used to describe price movements of a security, derivative, or currency. It originated from Japanese rice merchants and traders to track market prices and daily momentum hundreds of years before becoming popularized in the United States.

The chart is composed of individual “candles,” each representing a specific interval of time – for instance, one day or one hour. Each candlestick includes the following information:

• Open: The opening price at the beginning of the time interval.
• High: The highest price during the time interval.
• Low: The lowest price during the time interval.
• Close: The closing price at the end of the time interval.

These four elements form the basis of the candlestick, creating what appears to be a candle with wicks. The “body” of the candle is the range between the open and close prices, while the “wicks” or “shadows” represent the high and low prices.

If the close price is higher than the open price, the body of the candle is often filled (or colored differently), indicating a bullish (price rising) interval. Conversely, if the open price is higher than the close price, the body is often empty (or colored differently), indicating a bearish (price falling) interval.

Traders and investors use candlestick charts because they provide a lot of information at a glance and can help identify market trends and potential reversal points. The pattern of the candlesticks can form various known patterns that traders often interpret as indicators for price movement prediction. Examples of these patterns are Doji, Hammer, Engulfing, etc.
