Its donations for some of the coding that I do. Yes, the donations are small but they add up. Where can I find a wallet that consolidates the inputs into 1 output?
To sweep dust you need to raise transaction priority. Transaction priority
is a function of the age of the inputs and the size of the inputs. If you want to spend the dust you can either wait for the inputs to age a lot. Say a year or two. Or you can include a larger input in your transaction. So I suggest sending yourself 1 or 2 BTC to an address in your wallet, waiting a few days and then sending all the bitcoins including the dust transactions to another address in your wallet. The 1-2 btc input will push up the transaction priority and you won't have to spend as much in tx fees.
