Dust refers to small, leftover amounts of cryptocurrency that are often too insignificant to trade or transfer. These amounts typically result from transactions where the fee takes up more value than the remaining balance. For example, if you send a certain amount of Bitcoin and a fraction remains, that small amount can be considered dust. Users often find these tiny amounts frustrating, as they accumulate and can clutter wallets. Some exchanges or wallets may automatically convert these amounts into a more accessible form, but others require manual action.Moreover, dust may also be associated with security practices. Attackers sometimes use small amounts to track transactions and identify users involved in a chain. This is known as a dusting attack, where the intent is to surveil and potentially compromise privacy. In general, while dust itself may have little monetary value, its implications for usability and privacy are worth noting for those engaged in cryptocurrency transactions.
