Fun Facts

• Bitcoin was created by the pseudonymous Satoshi Nakamoto and the genesis block was mined on January 3, 2009, containing the text 'The Times 03/Jan/2009 Chancellor on brink of second bailout for banks' — a timestamp and a political statement embedded in the blockchain.
• The market capitalization of all cryptocurrencies peaked at approximately $3 trillion in November 2021. By January 2023 it had fallen to $800 billion — a 73% drawdown comparable to the dot-com crash of 2000-2002.
• Tax treatment of cryptocurrency varies significantly by country. In the US, the IRS classifies crypto as property (not currency) — meaning every trade, purchase, or receipt is a taxable event. The US Congress has been working on crypto-specific tax legislation since 2019.

FAQ

How is cryptocurrency taxed in the US?

Cryptocurrency is taxed as property by the IRS. Short-term capital gains (held < 1 year) are taxed at ordinary income rates. Long-term gains (held > 1 year) are taxed at lower capital gains rates (0%, 15%, 20% depending on income). Every sale, trade, or spend is a taxable event.

What is cost basis and why does it matter?

Cost basis is what you paid for the cryptocurrency including fees. Capital gain = sale price - cost basis. Accurate cost basis tracking is essential for correct tax reporting. For multiple purchases at different prices, FIFO, LIFO, or specific lot identification methods produce different tax outcomes.

What is dollar-cost averaging (DCA)?

DCA involves buying a fixed dollar amount of an asset at regular intervals regardless of price. It reduces the impact of volatility by averaging the purchase price over time. DCA is popular in crypto because of extreme price swings — it is implemented in most major exchange auto-buy features.
