All-Time-High (ATH)
The highest price a cryptocurrency has ever reached.
Altcoin

Bitcoin (BTC)
The first, most well-known, and largest cryptocurrency, created in 2009 by an anonymous person or group named Satoshi Nakamoto. Often considered "digital gold" and serves as a decentralized store of value.

Decentralization
The core principle of crypto. It means that no single company, bank, or government has control; instead, power is distributed among all network participants.

The first and most famous "memecoin," which started as a joke in 2013. Dogecoin has a large and loyal community and is often used for tipping and small transactions.

A fundamental piece of advice in the crypto world. One should never blindly rely on the opinions of others but always investigate projects for themselves.

An event that occurs approximately every four years where the reward for mining new bitcoins is cut in half. This reduces the supply and has historically often led to price increases.
HODL
An intentionally misspelled "Hold" that has cult status in the crypto scene. It describes the strategy of holding cryptocurrencies for the long term, regardless of short-term price fluctuations.
KYC (Know Your Customer)
The process by which exchanges like Binance are legally required to verify the identity of their customers (e.g., through an ID upload). It serves to combat money laundering.
Market Cap
The total value of a cryptocurrency. It is calculated by multiplying the current price per coin by the number of coins in circulation.
Memecoin
A cryptocurrency based on an internet meme or a viral joke. Examples include Dogecoin, Shiba Inu, or Pepe. Memecoins are often extremely volatile and rarely have any real technological utility.
Mining / Staking

Web3
The next generation of the internet, based on decentralized blockchain technologies. In Web3, users have more control over their data and digital assets.
Whitepaper
