Bitcoin: The Future, or World's Greatest Scam?

Bitcoin: A Story About Money

In this section, the speaker introduces bitcoin as the best money currently available because it's decentralized and cannot be stopped. The speaker also talks about how some people only invest in bitcoin to get rich without using it for transactions.

Introduction to Bitcoin

• Bitcoin is a decentralized network that took 12 years to become a trillion-dollar network.

• Some people only invest in bitcoin to get rich without using it for transactions.

• The speaker avoided looking into bitcoin until recently due to its ongoing saga and intrigue.

History of Money

• Payment first began with barter, which involved trading goods for other goods.

• Our ancestors realized that we needed a medium of exchange to represent the value of items they wanted to buy, such as cattle shells and eventually coins made of precious metals.

• Countries started using paper money backed by gold, known as the gold standard. In 1971, the US officially left the gold standard along with many other countries.

Fiat Money and Cypherpunks

• Today's money is no longer backed up by gold but rather our faith in government, known as fiat money.

• Emerging in the late 1980s, cypherpunks were against centralized authorities like governments being able to spy on people or have access to their information. They advocated for cryptography ways in which we're able to secure communication in the presence of third parties typically through encryption.

Conclusion

• The cypherpunks saw a clear contradiction between their values and the current financial system when they looked at banks or central banks.

The Origins of Bitcoin

This section explains the origins of Bitcoin and how it was created to solve the problem of trust in financial transactions.

The 2008 Financial Crisis and the Birth of Bitcoin

• The 2008 global financial crisis led to the collapse of major financial institutions, including Lehman Brothers.

• In 2008, a white paper titled "Bitcoin: A Peer-to-Peer Electronic Cash System" began circulating on a cryptography mailing list. It was written by someone under the pseudonym Satoshi Nakamoto.

• Nakamoto's nine-page manifesto laid out a framework using mathematics, computer science, and cryptography to create a currency that could be used for transactions without needing to trust a central authority.

Understanding Blockchain Technology

• Bitcoin is not a physical coin but rather entirely virtual - think of it as simply transactions on a ledger.

• Transactions are recorded on a ledger and verified by every computer on the network through complex algorithms.

• Instead of a central authority owning the ledger that records all bitcoin transactions, the ledger is distributed amongst all other computers or nodes in the bitcoin network.

• Each time a transaction is made on the ledger, every computer on the network will attempt to verify whether this transaction is legitimate by solving complex algorithms. When consensus is reached and the transaction is valid, it will be permanently stored on the ledger.

• After a certain amount of transactions are made on the ledger, a new ledger is created that contains code linking back to previous ledgers. This is why we call it blockchain technology.

Mining and Validating Transactions

• Individuals have both public and private keys, which are used to create and verify digital signatures without revealing the private key.

• The process of validating transactions on the block is known as mining. Miners receive a reward of a few bitcoins for every block they successfully mine, incentivizing them to continue adding to the blockchain.

• If someone attempts to hack or invalidate a previous block on the blockchain, they would end up invalidating every single block that comes after it, which would be easy to detect and reject by the network.

Conclusion

This section concludes with an explanation of how Bitcoin is a decentralized form of currency that allows you to see every single transaction that has ever been made since the very first block without being able to alter or change the records.

Decentralized Currency

• The bitcoin blockchain is a decentralized form of currency that allows you to see every single transaction that has ever been made since the very first block without being able to alter or change the records.

Bitcoin and Blockchain Technology

This section provides an introduction to bitcoin and blockchain technology, including the supply limit for bitcoins, resources for learning about bitcoin and blockchain technology, and how bitcoin reached its current price.

Introduction to Bitcoin and Blockchain Technology

• Nakamoto set the supply limit for bitcoins as 21 million within the software code itself.

• Skillshare is an online community with amazing classes that can help you learn about bitcoin and blockchain technology.

• Skillshare offers a class called "Demystifying Cryptocurrency: Understanding Bitcoin and Beyond" by Milton Demiros that explains some of the jargon in the cryptocurrency space.

• Skillshare costs about $10 a month for an annual subscription, which is the same price as two coffees a month. The first 1000 people to click on the link in the description of this video will get a free trial of Skillshare Premium.

How Bitcoin Reached Its Current Price

• Demand determines price. In early 2009, after releasing their infamous white paper, Nakamoto mined the genesis block setting into motion a series of events that would change its future forever.

• Early adopters included those from the cypherpunk movement who mined bitcoin just as a hobby until 2010 when Laszlo Hanyecz created a post on a bitcoin discussion forum offering to pay 10,000 bitcoins for two large pizzas. Two days later Laszlo reported that he had successfully traded his bitcoin for $25 worth of pizza. This was the very first recorded transaction in which bitcoin was used to purchase a tangible item.

• By the end of 2010, bitcoin had gone from being worth nothing to 39 cents, and the very first bitcoin exchange, Mt. Gox, was set up making it easier for people to trade their bitcoins with regular currencies.

• In 2011, bitcoin reached a price of one dollar and suddenly we began seeing the emergence of other cryptocurrencies using the very same blockchain technology that bitcoin uses. These alternative cryptocurrencies otherwise known as altcoins aim to solve their own problems by making changes to the original bitcoin.

Challenges Faced by Bitcoin

• There are currently thousands of altcoins out there and some of which are ponzi or pump and dump schemes that serve no use purpose.

• Bitcoin struggled in its early years from a poor reputation and multiple scandals. Its use of a private and public key system allowed for a level of anonymity which made it perfect for criminals and illegal use purposes.

• Silk Road was a notorious website on the dark web which engaged in buying and selling illegal substances with which bitcoins were used for transactions. The association of bitcoin with black markets like Silk Road put a stain on its reputation that can still be felt today. Another significant scandal during these years was the collapse of Mt. Gox, Bitcoin's first and biggest exchange, which at one point

The Rise and Fall of Bitcoin

This section covers the history of Bitcoin, from its early days to its peak in 2017 and subsequent crash. It also discusses the current institutional interest in Bitcoin.

Early Days of Bitcoin

• In 2014, Mt. Gox, one of the world's biggest Bitcoin exchanges, filed for bankruptcy protection after unexpectedly shutting down.

• Despite this setback, demand for Bitcoin remained with the launch of companies like BitPay, which provided mobile transactions for businesses wanting to accept Bitcoin.

• In 2013, speculation around cryptocurrency reached new heights as Bitcoin reached $1,000 at its peak before dropping into the hundreds.

The 2017 Bubble and Crash

• In December 2017, a single Bitcoin was worth almost $20,000 at its peak.

• However, within days after hitting its peak, Bitcoin began to tumble back down in price spurred on partly because of government crackdowns as cryptocurrency exchanges were banned in China.

• By December of that year (2018), bitcoin had fallen to just over $3,200.

Institutional Interest in Bitcoin

• Recent institutional interest in bitcoin is what is fueling the current insanity that we see today.

• PayPal's Venmo app will now allow its 70 million customers to buy hold and sell cryptocurrency.

• Tesla has put one and a half billion dollars into bitcoin and Musk will accept bitcoin as payment.

• More investors are looking at bitcoin as a store of value instead of a currency.

Criticisms of Bitcoin

• Some people believe that the price of Bitcoin is being manipulated to a great extent.

• Former PayPal CEO Bill Harris called the cryptocurrency "the greatest scam in history," noting that it is a pump and dump scheme.

Conclusion

• Despite criticisms, institutional interest in Bitcoin continues to grow. It's important to learn about Bitcoin and blockchain technology yourself, especially if you're going to invest in it.
