Arbitrage
Taking advantage of a difference in price of the same commodity on two different exchanges. Often mentioned when it comes to comparing ETH prices on Korean exchanges against US exchanges.
FOMO
Fear Of Missing Out. The overwhelming sensation that you need to get on the train when the price of something starts to skyrocket.
FUD
Fear, Uncertainty, and Doubt. Baseless negativity spread intentionally by someone that wants the price of something to drop.
FUDster
Someone that is spreading FUD.
Pump And Dump
The recurring cycle of an altcoin getting a ton of attention, leading to a fast price increase, and then of course followed by a huge crash.
Bagholder
Someone still holding an altcoin after a pump and dump crash. Can also just refer to someone holding a coin that is sinking in value with few future prospects.
Market Cap
The total value held in a crypto-currency. It is calculated by multiplying the total supply of coins by the current price of an individual unit.
ROI
Return on Investment. The percentage of how much money has been made compared to an initial investment. (i.e., 100% ROI means someone doubled their money).
TA
Trend Analysis or Technical Analysis. Refers to the process of examining current charts in order to predict which way the market will move next.
Volatility
It is a rate at which the price of a security increase or decreases for a given set of returns. Volatility is measured by calculating the standard deviation of the annualized returns over a given period of time. It shows the range to which the price of a security may increase or decrease.

General Cryptocurrency Terms
blockchain
Blockchains are distributed ledgers, secured by cryptography. They are essentially public databases that everyone can access and read, but the data can only be updated by the data owners. Instead of the data residing on a single centralized server, the data is copied across thousands and thousands of computers worldwide. More detailed information available at: https://en.wikipedia.org/wiki/Blockchain
Node A computer that possesses a copy of the blockchain and is working to maintain it.
Mining
The process of trying to ‘solve’ the next block. It requires obscene amounts of computer processing power to do effectively, but is rewarded with ether.
Mining rig
A computer especially designed for processing proof-of-work blockchains, like Ethereum. They often consist of multiple high-end graphic processors (GPUs) to maximize their processing power.
Fork
A situation where a blockchain splits into two separate chains. Forks generally happen in the crypto-world when new ‘governance rules’ are built into the blockchain’s code. Some more information available at: https://en.wikipedia.org/wiki/Blockchain#Hard_forks
Hard Fork
A Hard Fork is a radical change to the protocol that makes previously invalid blocks/transactions valid (or vice-versa), and as such requires all nodes or users to upgrade to the latest version of the protocol software.
Soft Fork
A Soft Fork is a change to the software protocol where only previously valid blocks/transactions are made invalid. Since old nodes will recognize the new blocks as valid, a softfork is backward-compatible. This kind of fork requires only a majority of the miners upgrading to enforce the new rules, as opposed to a hard fork which requires all nodes to upgrade and agree on the new version.
PoW
Proof-of-work. The current consensus algorithm used by Ethereum.
