Which of the following is NOT a feature of Bitcoin?

The correct answer is based on the economic characteristics of Bitcoin. Bitcoin is designed to be deflationary in nature rather than inflationary. This means that over time, Bitcoin’s supply is capped at 21 million coins, which encourages value appreciation as demand increases, while inflation typically refers to a continuous rise in prices and a decrease in purchasing power due to an excessive supply of money.

Decentralization is a core feature of Bitcoin, enabling transactions to occur without the need for a central authority, making it resistant to censorship and control. The limited supply directly contributes to Bitcoin's deflationary nature by ensuring that no more than 21 million bitcoins can ever exist. Pseudonymity allows users to transact without revealing their identities, adding a layer of privacy while still being traceable on the blockchain.

Thus, identifying inflation as a feature is not aligned with Bitcoin’s fundamental design and intended economic model, which is why it is the correct answer.
