This is not true , you must have a balance of 1 ETC on poloniex for any transaction to show, not the amount you send must be 1 ETC, if your balance IS +1 ETC on poloniex any amount you send will go through ok , just a fyi

something is also wrong with the pools ethc.coin-miners.info i mined 100mh/s for 6 hours straight , system says 0.23 earned and paid out , it did not arrive , and http://ethc.epool.io/ mined with 70 mh/s for 12+ hours , hardly earned anything and still no payout on pending balance ( its been pending 2 days ) supposed to be once a day payout.
