A coin is a cryptocurrency that operates on its own independent blockchain network, typically used for store of value, medium of exchange, and unit of account. Coins are issued through consensus mechanisms such as mining or proof-of-stake, featuring decentralization, security, and programmability, representing the base currency layer in blockchain ecosystems.
Leverage refers to the practice where traders borrow funds to increase the size of their trading positions, controlling assets of greater value with smaller capital. In cryptocurrency trading, leverage is typically expressed as a ratio (such as 3x, 5x, 20x, etc.), indicating the multiple of the original investment that a trader can control in assets. For example, using 10x leverage means an investor can control assets worth $10,000 with just $1,000.
