How to read this comparison
Size: compare market cap, not the price of one coin. A coin at $0.10 can be worth more in total than one at $100, if far more units exist.
Supply: a maximum supply means no new coins beyond a fixed number; "no fixed cap" means new coins keep being created, which spreads the value over more units over time.
Risk: both can move fast. Smaller coins usually swing harder, which is what volatility measures. A big move in the chart is history, not a forecast.

Is Cardano or Polkadot a better investment?
