💥 The Biggest Losses in Crypto History Several major events have caused massive financial damage, shaken investor confidence, and reshaped the crypto landscape. Here are some of the most notable ones: 🔥 1. Mt. Gox Hack (2014) Loss: ~850,000 BTC (worth billions of dollars today) What happened? At the time, Mt. Gox was the largest Bitcoin exchange. It was hacked and eventually went bankrupt. Impact: A huge blow to trust in Bitcoin. Prices plummeted. 🔥 2. Terra / LUNA Collapse (2022) Loss: Be...

BTC vs ETH Inflation Bitcoin (BTC) Maximum supply: 21 million BTC Current supply increase: Bitcoin block rewards (new BTC issuance) halve approximately every 4 years (“halving”) Annual supply increase as of 2025: Around 1.7% Inflation trend: Decreasing over time because block rewards diminish. By around 2140, all BTC will be mined, and inflation will approach 0% Ethereum (ETH) Maximum supply: Unlimited (theoretically no upper limit) Supply increase: With Ethereum 2.0 and EIP-1559, a “burn mec...

90% of “Flash Loan” attacks are not hacks in the technical sense, but rather actions carried out within the rules of the smart contract system itself. --- 📌 What does this mean? A flash loan allows users to borrow funds without collateral as long as the loan is borrowed and repaid within the same transaction block. The system prevents funds from being withdrawn before the transaction is completed. However, malicious actors can exploit this mechanism by manipulating price feeds or market dyna...

1. Cross-Chain Bridge
🌉 A protocol that enables asset transfers between different blockchains.
> “A digital bridge that moves your funds from Ethereum to Avalanche.”
⚠️ Risk: If hacked, funds on both chains could vanish.
---
2. Sidechain
🛤 A separate blockchain connected to the main chain but running with its own rules.
> “Like a side road with its own traffic lights, next to the main highway.”
Example: Polygon PoS Chain.
---
3. State Channel
An off-chain channel for transactions between two parties. Only the opening and closing are recorded on-chain.
> “Having a long chat on WhatsApp, but only writing the final summary into the ledger.”
---
4. Oracles
🔮 Services that bring external data into blockchains.
> “The eyes and ears of the chain.”
Examples: Chainlink, Pyth.
---
5. Sharding
🧩 A method of splitting a blockchain into smaller parts to process transactions in parallel.
> “Instead of making one person write the entire ledger, you divide the pages among many.”
---
6. Governance Token
🏛 A token that gives holders voting rights in a project’s decision-making.
> “The ballot paper of a DAO.”
Examples: UNI, AAVE.
---
7. TVL (Total Value Locked)
📊 The total value of assets locked in a DeFi protocol.
> “The amount of money stored in a protocol’s vault.”
---
8. Airdrop Farming
🚜 A strategy of actively using protocols to maximize chances of receiving future token rewards.
> “Planting seeds now to get free tokens later.”
---
9. Token Burn
🔥 Permanently removing tokens from circulation to reduce supply.
> “Burning money so the remaining becomes more valuable.”
---
10. Layer 0
🛠 The foundational layer that enables interoperability and infrastructure for multiple blockchains.
> “The blockchain of blockchains.”
Examples: Polkadot, Cosmos.
