So just today I got a little bit of ether into my account and have been trying to learn the ropes, and I've been trying to send it to my Poloniex deposit address, however it doesn't seem to be working at all.
I chose the option to pay the maximum transaction cost so it would be completed "in a few seconds" but it's been 7 minutes now and still 0 confirmations! Searching up the transaction hash gives "unable to locate transaction history" - http://etherscan.io/tx/0x1ec78202b153fb1b6292d8ee5f4d91cc6b018385edaa7ee2239bf1907fd6208e
What's wrong? please send help
EDIT: after another minute, the transaction just disappeared from my wallet app completely, wtf is going on?
