Cryptocurrencies
Cryptocurrencies, such as Bitcoin and Ethereum, are digital currencies based on the blockchain, a public ledger that doesn't depend on a central bank.
They are known for their volatility: they can gain or lose dozens of percentage points in a few days. They produce no profits or coupons, so their value depends only on supply and demand. That's exactly why they're the ideal field to practise without risking real money.
