In the cryptocurrency world, it's not enough to just buy tokens. Here, even the size of your wallet can determine your 'status' in the ecosystem. If yesterday we talked about whales - huge players who move the market with a single move, today we will analyze who shrimp, fish, and dolphins are.

If someone writes 'To the moon!' in crypto chats or on Twitter, or simply posts a rocket 🚀, it means one thing — an expectation of a sharp and rapid price increase of the asset. The word Moon in slang has become synonymous with 'the price that is flying into space.'
Origin
The phrase originated in the early years of Bitcoin. The community joked that someday its price would 'fly to the Moon'. Over time, the meme solidified and became a universal symbol of hope for growth.

In the cryptocurrency world, the word whale is used to refer to investors who hold such large sums in crypto that their actions can literally shake the market. This term comes from gambling: in casinos, a 'whale' is a very wealthy player making huge bets. In crypto, the analogy is obvious — a large player who can create a 'storm' with one movement.

FUD stands for Fear, Uncertainty, Doubt. It is one of the most common terms in crypto slang, and it is not only about emotions but also about a whole strategy to influence the market.
The essence of FUD
FUD is the intentional or unintentional spreading of negative information that causes people to doubt the project, sell assets, or simply be afraid to enter a trade. Sometimes FUD can be true (for example, real bugs in the code or news about regulation), but more often it is rumors, exaggerations, or outright manipulations.

FOMO (Fear Of Missing Out) is not about the market, it’s about the brain. In crypto, it manifests particularly vividly: candles soar up, the feed is full of "x’s", the chat is already "in the rocket", and you are not yet. Hands reach to buy "anything", while it’s not too late. Below is what exactly happens to us and how to stop being fuel for others' pumps.

HODL is one of the most iconic words in crypto slang. It means a strategy where an investor does not sell their cryptocurrency, even if the price drops or rises significantly, and there’s panic around. It’s not just "holding coins", but an entire philosophy: faith in the long-term success of the technology and the project.
How it started:

From p2p lending to a leader in lending without intermediaries.
Aave — one of the flagships of decentralized lending. It all started with ETHLend — a p2p lending project created by Finnish developer Stani Kulechov in 2017. In 2020, it transformed into Aave (translated from Finnish as 'ghost') and became a true giant in DeFi.

While Tether (USDT) is often accused of opacity, USDC positions itself as a "clean" and auditable stablecoin. It was created in 2018 by the Centre consortium, which includes Circle and Coinbase, and quickly gained the trust of major players.
The main goal of USDC is to provide a stable, regulated alternative to the US dollar on the blockchain. One USDC should always be backed by 1 real dollar (or its equivalent) in reserves held in bank accounts and short-term US government bonds.

Chainlink (LINK) is a bridge between blockchains and the outside world
Smart contracts are great, but there is a problem: they are 'blind'. They cannot fetch data from the outside world themselves — for example, the price of ETH in dollars or the result of a soccer match. This is where oracles come in, and Chainlink is the main player in this field.

Polkadot (DOT)
Polkadot is not just another blockchain network. It is a foundation for an entire ecosystem that brings different blockchains into a single space. The idea belongs to Gavin Wood, one of the co-founders of Ethereum and the author of the Solidity language. His goal is to solve the main problem of blockchains: the lack of interoperability between networks.

Towns Protocol (TOWNS) is a decentralized protocol for creating next-generation chat spaces. It combines a messenger, NFT community, interest groups, and Web3 monetization in one space.
Each community (called 'Space') lives on smart contracts, is governed in a decentralized manner, and supports:

What is Succinct?
Succinct is a decentralized network of proof providers (provers) based on Ethereum that simplifies and speeds up the creation of zero-knowledge proofs (ZKP) for any applications. Through an open marketplace model, Succinct allows requesters and providers to conduct auctions for generating proofs offline with subsequent secure settlement on-chain.

When we talk about cryptocurrencies, most people immediately think of Bitcoin. But the real technological breakthrough actually began with Ethereum — not just a cryptocurrency, but a whole decentralized platform for creating applications that work without third-party involvement.
At the core of Ethereum is the concept of smart contracts.

PoW vs PoS: how consensus works in blockchain?
After we understood what consensus is, it's time to move on to the two most popular algorithms:
1. Proof of Work (PoW)
Essence: miners compete to solve a complex problem to add a block.
Security: high, as an attack requires enormous computational power.

What are oracles in blockchain? (and why they are essential for DeFi, GameFi, and more)
Blockchain is a closed system. It does not know what the weather is today, who won the match, or how much a dollar costs. But what if a smart contract needs this information?
Here come the oracles - the bridge between the blockchain and the outside world.

In the world of cryptocurrencies, blockchain openness is both a blessing and a potential risk. Every user can view any transactions, wallet balances, and token movements. But how to use this safely without revealing yourself and your actions?
Here are the key principles:
1. Use blockchain explorers wisely

When transactions on Ethereum became expensive, developers came up with Rollups — second-layer solutions that 'roll up' (bundle) numerous transactions into one package and send it to L1. This saves space and reduces fees.
What is a Rollup?
Batch transactions: dozens of operations are gathered into one block.

🔥 Error #1: Going all in
What happens:
Beginners often buy tokens after hearing 'pump' on Telegram or YouTube. Without analysis, without strategy, with all their money.
How to avoid:
Start with small amounts to understand the market.
Always keep cash in USDT/USDC in case of a dip.
Stick to the 10% rule: don't invest more than 10% of your portfolio in one asset.

Bitcoin — from digital manifesto to global asset
When the world plunged into a financial crisis in 2008, public trust in banks and regulators was undermined. Against this backdrop of instability, a mysterious figure under the pseudonym Satoshi Nakamoto emerged, publishing a white paper titled "Bitcoin: A Peer-to-Peer Electronic Cash System." This was not just a technical document — it was a challenge to the established system.

Zero-Knowledge technologies have long ceased to be just 'cryptographic exoticism' — today they are becoming the core of Ethereum's scalability. This is especially evident in the case of StarkNet and Scroll — two advanced ZK-rollup solutions that are pushing the industry forward, but do so differently.
