The Chainlink circulating supply chart represents the total number of Chainlink (LINK) tokens actively available in the market and not locked in any contract. The graph fluctuates based on the rate of token release, token burns, and movements from inactive to active wallets. Traders can use this chart in tandem with pricing trends. A decrease in circulating supply can imply scarcity and may drive prices up if demand remains constant or increases. Conversely, an increase could signal oversupply, potentially leading to price decreases if the demand isn't keeping up. It's all about matching supply trends with price action to predict future movements.
