Outputs per day : Total transaction outputs per day and it includes coins returned to the sender as change and excludes coinbase transaction (miner reward)
Dust: An amount of cryptocurrency smaller than the fee required to process it. Since the value of both the currency and the transaction fee vary, the demarcation between dust and a usable amount of currency fluctuates. For reference, as of March 2019, Bitcoins transaction fees are between $0.20 and $0.28 (or 0.00005089 - 0.00007125 BTC). Transactions of lesser value than this are considered dust because they will not be processed by the network.
IEO: Initial Exchange Offering. A fundraising event for early-stage crypto projects administered by an exchange (or group of exchanges). Similar to an ICO, but with a direct listing on a crypto exchange which acts as the counterparty. Projects launched on Binance’s Launchpad, such as BTT and Fetch.ai are examples of IEOs.
