Blockchain: The authoritative record of every Bitcoin transaction that has ever occurred.
Block Halving: refers to the Block Reward being halved. For example BTC used to have a Block Reward of 50BTC it then drpped to 25BTC and is now at 12.5BTC. For miners it means a big drop in value.

Sharding: Related to Ethereum. It is a database partitioning technique that will be used to dramatically scale ethereum’s blockchain and enable it to process more transactions per second.
Smart Contract: is an agreement between two people in computer code run on the blockchain, so they can’t be changed. The transactions that happen in a smart contract processed by the blockchain mean they can be sent automatically without a third party.
Soft Fork: is a change to the software protocol where only previously valid blocks/transactions are made invalid. Since old nodes will recognise the new blocks as valid, a soft fork is backward-compatible. This kind of fork requires only a majority of the miners upgrading to enforce the new rules.
Token: represent a particular fungible and tradable asset in the Crypto world.
Total Supply is the total amount of coins in existence right now.
Transaction: An entry in the blockchain that describes a transfer of bitcoins from address to another. Bitcoin transactions may contain several inputs and outputs.

-Trading Terms-
(Cryptonomics does not provide an in depth tutorial on trading, but outlines the most common terms related to trading in the cryptocurrency space.)
Arbitrage: is buying a coin low and selling the coin high. Sometimes different exchanges have different values for the coins which allows for arbitrage trading. It sounds easy in theory but watch out the the exchange fees.
ATH (All Time High): The highest value a particular coin has reached.
Bear Market: – When the Market is on a downwards trend, and the sentiment is persimistic, traders are selling off, and noone is buying to create a rally in prices.
Bollinger Bands: are a type of statistical chart characterising the prices and volatility over time of a coin using a method created by John Bollinger.
Bull Market:- When the Market is on a upwards trend, and the sentiment is optimistic, and prices are on the rise.
Dead Cat Bounce: is when a coin temporally increases  after a sharp downturn, to only fall further. Eg $1000 to $500 to $600 to $300.
Dip: -The perceived low point or price in the market trend.
Fibbonnaci:- A commonly used analysis tool used to measure the percentage of gain and loss of a coin, to determine a good percentage to buy or sell at.
Fundamental Analysis: aims to determine whether a particular coin is a viable investment. Due to the variability in the crypto space this is done differently to the tradition stock market. In effect it is completing your research.
MACD (Moving Average Convergence/Divergence Indicator): It is a trend following indicator. It is used to identify new trends in the markets and investigate if a coin is worth purchasing.
Margin Trading: Many exchanges will give you the opportunity to Margin Trade. In essence, you are borrowing money to increase your capital to make bigger/more trades to make more profit. However, this also means you are increasing the amount you can lose. The exchange will always want there money back plus fees/interest. Not recommended for the newbie.
Order:- An request placed on an exchange to buy or sell a coin or token at a defined price
Pair:- When one currency can be sold or bought for another. eg AUD/BTC Bitcoin can be bought or sold for AUD or BTC/ETH Bitcoin can be bought or sold for Etherium.

Return on Investment (ROI): the way to calculate the ROI is: (Total Return – Initial investment) / Initial Investment. Eg (150-100) / 100 = .5 or 50%
Shorting: Is when you sell a coin hoping it will go down. It is often done by “borrowing” a coin and selling it then buying it pack at a cheaper price therefore making a profit. If however the coin goes up instead of down you make a loss.
STMA:- Short term moving average
Stop Loss:- A sell at a minimum price you want to sell for, it will only be triggered if the price falls down to this point from a previous higher price.
TA:- Technical analysis
Whales: Are powerful investors. An individual is considered a whale when he/she is powerful enough to significantly change the value of a coin. When you see an extreme and sudden jump on the chart of your coin, it is likely that there are one or more whales together influencing the value.

Lambo: In the height of Bitcoins 2014 rise in value, some early adopters of bitcoin were able to purchase Lamborghini’s directly for bitcoin, while we are not sure if this was the origin of the term, but everyone is excited about the prospect of getting rich in bitcoin/crypto to buy “lambos”
Moon: -A common slang term in the community, crypto enthusiasts believe that at a coin will rise in value “to the moon”. the term is quite often accompanied by pictures of rocket ships heading to the moon.
Rekt: -buying the highest prices in the market just before the fall in price.
