Crypto Masterclass: Bitcoin, Altcoins, NFTs, DeFi, Metaverse

Analyze how the 2008 financial crisis, driven by deregulation and subprime mortgages, shaped the environment surrounding bitcoin's birth.

Examine the birth of Bitcoin: the 2008 white paper by Satoshi Nakamoto, explore the mystery of the creator, and consider motivations like privacy, security, and disruption of current financial systems.

Explore the Bitcoin white paper to understand its decentralized, peer-to-peer electronic cash design, including description of the transaction, the Bitcoin network, and the reward system.

Understand how bitcoin transactions form a blockchain by grouping verified transactions into blocks and explore mining that creates new bitcoins from the genesis block to block one.

Define bitcoin as a decentralized digital currency native to the internet, transferred peer-to-peer without intermediaries, secured by cryptography and mined rewards on the blockchain.

Bitcoin operates decentralization, enabling transactions without central authorities or intermediaries. It features transparency, fast cross-border transfers, a finite 21 million cap, and cryptographic security with private keys and anonymous wallets.

Bitcoin is not a physical coin; it rewards solving complex mathematical puzzles using high-capacity machines. Ownership resides in wallet addresses on the blockchain.

Demonstrates how a bitcoin transaction transfers funds between wallets using private and public keys, addresses, and a peer-to-peer blockchain secured by mining and proof of work, making transactions irreversible.

Break down the ten steps of a bitcoin transaction to help you understand the process, with the next lecture covering related concepts.

Explore how double spending affects digital currencies and how Bitcoin's blockchain and a decentralized ledger enable nodes to verify transactions and prevent spending more than owned.

Understand digital Bitcoin mining as the process of validating new blocks, rewarding miners with Bitcoin, and securing the network by recording transactions in a blockchain.

Bitcoin miners earn block rewards that govern supply, with a 21 million cap and halvings every four years, from 50 to 25 to 12.5 to 6.25, 3.125 in 2024.

Explore how the Bitcoin halving cycle, every four years, drives miners to invest in electricity as block rewards shrink. Note price spikes around halving followed by subsequent crashes.

Clarify mining terminology used in the crypto space, including hash rate and hash power, and explain what these terms mean.

Discover how bitcoin mining machines, from GPUs to ASICs, use computational power to solve complex math puzzles that yield a hash, earn bitcoin, and secure transactions.

Explore how hash power drives miners to solve complex puzzles and create new blocks. Bitcoin adds a new block every 10 minutes, up to 1 megabyte with about 4,000 transactions.

Measure the hash rate to gauge the network's computational power and security, and understand mining speed in hash per second.

Explore how hashing functions, as hashing algorithms, protect passwords and payment data by turning strings into fixed-length hash values, with Bitcoin's SHA-256 as a one-way, irreversible example.

Hash values arise from a hash function and an algorithm, stay the same length for any input, acting as the fingerprint of a transaction, typically shown as 64 hexadecimal characters.

Explore how miners use power to solve challenges, generating a 64-digit hash below a block’s target and earning bitcoin when the block is validated and added to blockchain with timestamps.

Discover the basics of bitcoin mining. Set up a digital wallet, select mining software, and secure mining hardware, while considering electricity costs and rising competition that cut rewards.

Explore how Bitcoin shapes economies, from peer-to-peer cash systems to varied national responses, and contrast value versus price while examining the role of Bitcoin exchanges.

Discover how Bitcoin derives value from its inherent qualities and serves as an alternative to traditional financial systems and payment methods.

Explore how demand and supply drive bitcoin's price volatility, influenced by media, altcoins, and external events, with examples of price spikes and crashes.

Bitcoin trades on crypto exchanges that offer lending, borrowing, and saving, with Binance and Coinbase highlighted as top platforms and leaders Changpeng Zhao and Brian Armstrong.

Clarify the difference between blockchain and bitcoin and define these terms for beginners. Explain how blockchain underpins bitcoin and address common mix-ups novices have.

Explore how Bitcoin functions as a decentralized digital currency, enabling anonymous Bitcoin transfers without banks or governments, and why its design relies on blockchain technology.

Understand how blockchain uses blocks as ledger pages, storing unalterable transaction data across networked nodes to ensure transparency, security, and prevention of double spending.

Explore how a block's cryptographic hash, timestamp, and transaction data form an immutable record, while Merkle trees organize blockchain data securely, with terms like private key and public key introduced.

Explore how bitcoin addresses function as alphanumeric strings linked to a wallet to send and receive bitcoins, with the digital home address analogy.

Discover block height as the number of blocks connected in a blockchain, and how a specific location is measured by the count of preceding confirmed blocks.

Block rewards are the coins, Bitcoin, and transaction fees given to miners for finding the correct 64-character hash, verified by the network, as proof of work.

Encryption transforms plaintext into cipher text and uses a key to unlock it, enabling secure data transmission in blockchain; decryption reverses this to reveal the plain text.

Explore private and public keys in cryptocurrency wallets: private keys sign transactions and must stay private to prevent theft; public keys can be shared and act like an address.

Explore bitcoin wallets as digital tools that interact with the blockchain, storing cryptographic keys to access addresses, send and receive bitcoins, and understanding their categories and varieties.

Differentiate hot wallets and cold wallets by their internet dependence: hot wallets require internet to operate, while cold wallets work offline.

Explore software wallets as hot wallets connected to the internet, including mobile wallets like Binance and web wallets such as Exodus, alongside hardware and paper wallets.

Understand the hardware wallet, a physical device like a usb key that stays offline as a cold wallet, offering the most secure option for storing bitcoin.

Paper wallets present a cryptocurrency address and private key as QR codes on a sheet of paper, but this method has many flaws and is considered obsolete.

Assess how bitcoin's status as legal tender varies worldwide, from outright bans to formal recognition, and compare how nations regulate or adopt it as a medium of exchange.

El Salvador officially adopts bitcoin and plans a bitcoin city, amid questions of feasibility. India leads mining and ownership with 100 million users, drawing interest after China's crypto stance.

Weigh the advantages and disadvantages of bitcoin, including its finite deflationary supply, potential high returns, and growing use as a medium of exchange amid regulatory questions and price volatility.

Explore cryptocurrencies, including Bitcoin and altcoins, understand investing strategies, and learn essential terminology to make informed financial decisions.
