“Milli” is a prefix used to denote one-thousandth (1/1,000) of a unit. In cryptocurrency, it often refers to smaller denominations of a coin or token. For instance, when discussing Bitcoin, a milliBitcoin (mBTC) represents one-thousandth of a Bitcoin, or 0.001 BTC.Using milli as a term helps to makes transactions more manageable, especially when dealing with highly valued currencies. It allows users to better understand and express smaller amounts without always referencing complete coins.As cryptocurrency values can fluctuate significantly, breaking down units into smaller parts makes it easier for people to participate, especially in cases where the whole unit might be worth a large sum. This practice is also common with other cryptocurrencies, as many have similar denominations for easier transactions and pricing.
