Proxy here, Proxy there, Proxy is now everywhere.
The word proxy comes from Latin (*procuratio* = representation) and generally means representative, substitute, or intermediary – something that acts instead of you or on your behalf.
In different fields:
1. General / everyday use
Someone or something that represents you (e.g. “I sent a proxy to the meeting” = someone voted for me).
2. IT and internet (the most common meaning today)
Proxy server – a computer that stands between you and the internet.
Hides your IP address (anonymity) Speeds up page loading (caching) Bypasses blocks (e.g. school/firewall proxy)
Example: Using a VPN? That’s actually a special type of proxy.
3. Law and business
Proxy voting – when someone votes for you at a company meeting or shareholders’ meeting (you give them power of attorney).
4. Programming
Proxy pattern – a design pattern where one class represents another (e.g. controls access, logs calls, or delays loading heavy objects).
5. Science and ecology
Proxy data – an indirect indicator (e.g. in paleoclimatology: tree rings or ice isotopes serve as a “proxy” for temperature thousands of years ago).
Human summary:
Proxy always means something that works instead of something else. Today you hear it most often in the context of the internet (“use a proxy”).

Hi! 😊
The Fear & Greed Index (Crypto Fear & Greed Index from alternative.me, the same should apply to Binance) is calculated daily and is based on 6 indicators that together give a score from 0 to 100.
How is it calculated exactly?
Each indicator has its own weight and compares current data with the historical average. The results are summed up and normalized into one final number.
What does it come from? (factors + weights)
Volatility – 25 % Momentum and trading volume – 25 % Social media (mainly Twitter/X) – 15 % Surveys – 15 % (currently paused, so not counted) Bitcoin dominance – 10 % Google Trends – 10 %
What period does it cover?
Simply put: The index tracks whether the market is currently “panicking” or “going crazy with greed”, and is mainly based on Bitcoin’s behavior over the last 1–3 months. Most data (volatility, momentum, volume) looks at the past 30 and 90 days, while social media, dominance and Google Trends use very recent data (days to weeks).

Ciao! 😊
Uno strumento classico che misura il sentiment nel mercato delle criptovalute (principalmente Bitcoin). Ecco una spiegazione breve e chiara:
Cosa significa?
È un numero da 0 a 100 che mostra se il mercato è dominato più dalla paura o dall'avidità. Viene calcolato automaticamente da 6 fattori (volatilità, volume di scambio, social media, dominanza BTC, Google Trends e sondaggi).
Come si legge?
0–24 → Paura Estrema
25–49 → Paura
50 → Neutro
51–74 → Avidità
75–100 → Avidità Estrema
Come si usa?

DeFi is a system of financial tools and services built on smart contracts on blockchain (mainly Ethereum), without the need for intermediaries like banks or exchanges. It enables lending, borrowing, speculation on asset prices (derivatives), cryptocurrency trading, risk insurance, and yields from savings. It's a layered architecture with high composability (composite blocks), but it brings high risks like code errors or hacks. DeFi protocols have varying degrees of decentralization – some are truly neutral, others are subject to manipulation or regulation like traditional finance.
History
DeFi originated in blockchain and fintech, with decentralized exchanges (DEX) as an alternative to traditional payments. Smart contracts spread with Ethereum in 2017. Key projects: MakerDAO (2017, lending stablecoin DAI, renamed to Sky in 2024 with USDS; circulating supply ~9 billion USD in March 2025). In June 2020, Compound launched yield farming, leading to a boom. By September 2020, DeFi accounted for 2/3 of crypto market price changes with 9 billion USD in collateral. Peak TVL (total locked value) 178 billion USD in November 2021, drop below 40 billion in 2023. Investors like Andreessen Horowitz poured in billions. In May 2025, Aave holds 45% of TVL (~25.4 billion USD).
How It Works
DeFi runs on decentralized applications (DApps) on blockchain, with transactions between users via smart contracts or open software. Access via wallets like MetaMask. DApps connect for complex services – e.g., stablecoins are lent into liquidity pools in protocols like Aave, where interest rates change based on demand. Oracles are used for external data (asset prices). Examples: flash loans (without collateral, repaid in one transaction), Uniswap (DEX with liquidity pools, where liquidity providers earn from fees without KYC).
Key components:
Smart contracts: Automate loans, trades.DEX: Peer-to-peer or AMM (automated market maker) without intermediaries.Lending protocols: Dynamic interest rates, e.g., MakerDAO for stablecoins.
Advantages
DEX reduce theft risk (no need to send assets to an exchange), offer anonymity without KYC. Average weekly trading volume on DEX in mid-2025: 18.6 billion USD, with 9.7 million unique wallets. Greater accessibility and higher yields.
Risks and Criticism
Code errors, hacks, and irreversible transactions are common. Anonymous founders can disappear with funds (rug pulls). In 2021, half of crypto crime was related to DeFi (129 million USD in hacks). Risks: complexity for users, impermanent loss (loss for liquidity providers), slippage, front-running. Decentralization isn't always real – upgradable contracts allow manipulation. Governance via DAO often concentrated in few hands. Regulation: SEC lawsuits (e.g., EtherDelta 2018), FATF recommendations from 2021.
Significant Events and Statistics
Bancor hack (2018): loss of 13.5 million USD.TVL peak: 178 billion (2021), drop below 40 billion (2023).DeFi scams: 129 million USD in 2021.DEX volume: 18.6 billion weekly (2025).
Future
DeFi faces regulations (FATF 2021). The Economist (2022) sees a three-way battle between Big Tech, state digital currencies, and DeFi. Regulatory challenges in the US with 2.5 trillion USD in crypto. Future: potential for decentralized financing, but risks of scams and regulations.
