Crypto Basics, Part 17 📤
What actually happens when you hit send?
Your transaction joins a queue. Miners verify it and bundle it into a new block.
Once that block joins the chain, you get your first confirmation.
Each block after adds another.

Crypto Basics, Part 16 🔑
What happens if you lose your private key? Your crypto doesn't disappear.
It stays on the blockchain, visible to anyone. You just can't reach it.
No reset. No support line. No way back in. That's why the recovery phrase matters.

What makes a blockchain so hard to tamper with? 🧊
Cryptography: each block carries a fingerprint of the last.
Distribution: thousands of copies, no single target.
Consensus: the network must agree before anything is added.

Crypto Basics, Part 14 🤝
The price you can buy at is never quite the price you can sell at. That gap is the bid-ask spread.
Bid: the most buyers will pay.
Ask: the least sellers will accept.
A trade happens the moment they finally meet.

What are NFTs?
Non-Fungible Tokens (NFTs) are unique digital assets that represent ownership of specific items or content on a blockchain. Unlike cryptocurrencies, they are not interchangeable, and each NFT has distinct properties that make it one of a kind.
Why Do Different Cryptocurrencies Exist?
Different cryptocurrencies are designed to solve different problems. Some focus on payments, others support smart contracts, decentralized applications, privacy, gaming, or cross-border transfers.
What are Smart Contracts?
Smart contracts are programs stored on a blockchain that execute automatically when predefined conditions are met. They eliminate the need for intermediaries by enforcing agreements through code, making processes more transparent and efficient.
What Makes a Blockchain Secure?
Blockchains use cryptography, decentralization, and network consensus to protect data. Because many computers maintain the same record, changing information is extremely difficult without network agreement.
What Happens When You Send Crypto?
When you send cryptocurrency, your transaction is broadcast to a blockchain network where it is verified by validators or miners. Once approved, the transaction is added to the blockchain and becomes part of a permanent public record.
Why Does Bitcoin Have Value?
Bitcoin has value because people are willing to use, hold, and exchange it. Unlike traditional currencies, Bitcoin is not issued by a government. Its value comes from factors such as limited supply, network security, adoption, and market demand. Similar to gold, scarcity plays a major role in how people perceive its worth.
What is Blockchain?
Blockchain is a distributed digital ledger that records transactions across a network of computers. Each block is linked to the previous one, forming a secure chain of data. Because it’s decentralized, no single entity controls it, and once information is recorded, it’s extremely difficult to change.
What is a Crypto Wallet?
A crypto wallet is a tool that allows users to interact with blockchain networks. It stores private keys, which are used to access and manage digital assets. Wallets can be hardware-based, software-based, or even paper formats.
What is DeFi?
Decentralized Finance (DeFi) refers to financial systems built on blockchain networks that operate without traditional institutions. It includes applications for lending, borrowing, trading, and earning yield, all managed through smart contracts.
