The words to understand crypto, with real data.
Each term has a simple explanation, a more technical one and a chart built from prices that actually happened.
How an investment is measured
Volatility
How much a price moves from one month to the next, up or down. More volatility means bigger jumps.
Worst drop
The biggest fall from a peak to the lowest point that came after it, before recovering.
Annual return
The steady yearly rate that leads to the same final result as the real path, with all its ups and downs.
Accumulated return
How much an investment grew in total, from start to finish, without splitting it by year.
Investing over time
Compound interest
Earning on what you've already earned: gains are reinvested and, over time, produce gains of their own.
Buying a little every month (DCA)
Investing the same amount at regular intervals, without trying to guess the best moment.
Average cost
What you paid on average for each unit you own: the total invested divided by what you bought.
Holding (HODL)
Buying and keeping an investment through the ups and downs, without selling in a panic.
How to read charts and projections
Logarithmic scale
A scale where each mark is worth ten times the one before: a rise from 1 to 10 looks the same as one from 1,000 to 10,000.
Range of outcomes
Instead of a single number, the spread of possible results: the pessimistic, typical and optimistic cases.
Block bootstrap
Building possible futures by copying one-year stretches of real history, in a different, random order.
Bitcoin and the stock market
Sat
The smallest unit of bitcoin: one bitcoin is 100 million sats.
Halving
The moment, roughly every four years, when the number of new bitcoins created is cut in half.
S&P 500
An index of 500 of the largest US companies. It's used as the thermometer of the stock market.
ETF (exchange-traded fund)
A fund you buy and sell on the stock market like a share, which holds many investments at once.
