Annual Percentage Rate (APR) is a financial metric expressing the percentage of interest earned or charged over a one-year period without accounting for compounding effects. In cryptocurrency, APR measures the annualized yield or cost of lending platforms, staking services, and liquidity pools, serving as a standardized indicator for investors to compare earnings potential across different DeFi protocols.
Fear of Missing Out (FOMO) is a psychological state where investors fear missing significant investment opportunities, leading to hasty investment decisions without adequate research. This phenomenon is particularly prevalent in cryptocurrency markets, triggered by social media hype, rapid price increases, and other factors that cause investors to act on emotions rather than rational analysis, often resulting in irrational valuations and market bubbles.
NFT (Non-Fungible Token) is a unique digital asset based on blockchain technology where each token possesses a distinct identifier and non-interchangeable characteristics, fundamentally different from fungible tokens like Bitcoin. Created through smart contracts and recorded on the blockchain, NFTs ensure verifiable ownership, authenticity, and scarcity, primarily applied in digital art, collectibles, gaming assets, and digital identity.
Leverage refers to a financial strategy where traders use borrowed funds to increase the size of their trading positions, allowing investors to control market exposure larger than their actual capital. In cryptocurrency trading, leverage can be implemented through various forms such as margin trading, perpetual contracts, or leveraged tokens, offering amplification ratios ranging from 1.5x to 125x, accompanied by liquidation risks and potential magnified losses.
