Cardano vs 
Polkadot
Two research-led platforms founded by Ethereum co-founders who left to build differently. Cardano is a single chain built in deliberate, peer-reviewed phases. Polkadot is explicitly many chains: parachains with their own rules that share Polkadot's security and can pass messages between each other. One bets on getting a single chain right; the other on a network of specialised chains.

FAQ
Which is bigger, Cardano or Polkadot?
By market value today: Cardano (A$12.7B vs A$2.7B). Size measures money invested, not quality — but it does measure liquidity, which affects how easily you can buy and sell.
Which performed better this year?
Over the past 12 months in AUD terms: ADA −72.9%, DOT −74.5% — the chart above shows the whole path, which matters more than the endpoints. Past performance is no indicator of future results, in either direction.
Can I buy both in Australia?
Yes — both are listed on AUSTRAC-registered exchanges we verify. ADA appears on 3 of our reviewed platforms and DOT on 3. Compare costs first on the fee calculator, and remember every crypto-to-crypto swap between them is a CGT event.
Should I hold ADA or DOT?
That's a personal decision we don't make for you — this page exists to make the structural differences clear so the choice is yours. What we'd say to anyone: understand what job each coin is designed for, size positions like the risk is real, and check the honest failure statistics before going further down the market-cap list.
