Protocol
In crypto, a protocol is the underlying set of rules that governs how a blockchain works, the code that defines how transactions are validated, how consensus is reached, and how the whole network behaves. Bitcoin and Ethereum are protocols; so are the decentralised finance applications built on top of them.
The word borrows from computing, where a protocol is any agreed standard that lets systems talk to each other, and in crypto it captures the idea that the rules, not any company, run the show.
Example: A developer builds a lending application as a protocol, a set of self-executing smart contracts that let users borrow and lend without a bank in the middle. Anyone can interact with it directly, the rules are transparent and enforced by code, and the extent to which a central operator can change the terms depends on the protocol’s governance mechanisms, which is precisely what people mean when they talk about trusting the protocol rather than trusting a company.
Pseudonymous
Pseudonymous means acting under a persistent identifier rather than your real name, and it describes how most cryptocurrencies actually work. Bitcoin is often called anonymous, but that is not quite right: every transaction is public and permanently recorded, linked to an address rather than a name.
The address is a pseudonym. As long as no one connects it to you, you have some degree of privacy, but the moment that link is made, your transactions associated with that address may be traceable.
Example: A Bitcoin user sends and receives coins through an address that reveals nothing about who they are, so their activity is pseudonymous rather than truly anonymous. But if they ever cash out through an exchange that knows their identity, or otherwise tie the address to their name, investigators may be able to trace transactions associated with that address, since the whole history sits permanently on the public ledger for anyone with the patience to follow it.
Psychology
Psychology, in trading, is the mental game, and most veterans will tell you it matters more than strategy. Fear and greed are the two great enemies: fear makes you cut winners too early and freeze when you should act, while greed makes you hold losers hoping they come back, over-leverage, and chase.
Discipline, patience, and the ability to stick to a plan when money is on the line can help traders manage risk, no matter how good their analysis.
Example: A trader has a sound strategy but keeps sabotaging it, panicking out of good trades at the first wobble and doubling down on losers out of stubborn pride. Her problem is not analysis but psychology: poor emotional control can undermine even a well-designed trading system, which is why experienced traders work on their mindset as hard as they work on their charts.
Publicly traded
A company whose shares are available for purchase on a stock exchange.
Pullback
A temporary reversal following a surge.
Pump
A pump is a sharp, often engineered surge in a price, driven by a burst of buying, hype, or coordinated manipulation rather than any real change in value. In crypto especially, the word is shorthand for a coin rocketing higher, and it comes loaded with suspicion, because pumps can be the setup for a dump, where the organisers who drove the price up sell into the frenzy and leave latecomers holding the bag.
Example: A little-known token suddenly pumps thirty percent in an hour as a wave of hype floods social media and buyers rush in for fear of missing out. Seasoned traders eye it warily, suspecting a classic pump-and-dump: a group may have quietly accumulated the coin, whipped up the excitement to draw in buyers, and may now be selling into that demand, so the same price that rose sharply could decline just as fast once the organisers have cashed out.
