Why the heck would you bother to send that amount of dust?  Did coinbase not indicate the transaction fee it was going to give to the miners on your behalf?  It is because of people like you making these pointless transactions that we are facing this bloated mempool and the ridiculous transaction fees.  Can you make this a learning experience at least, and study what it is you are doing to the blockchain and the mempool?

Two sites for you to learn from (please do not transact BTC until you learn them):

 This shows how much folks can expect to be paying to send 47$ coinexchange (for whatever reason I don't know):

This shows how long folks can currently expect to wait if they don't pay 29$ to send 18$ to coinexchange:

I am sorry for your painful lessen, but this is the way it is going to be, until a) the noobs stop clogging the mempool with 47$ transactions b) the blocksize gets expanded c) noobs learn and switch over to LTC, BCH or any other perfectly acceptable substitute.
