P.S.A Do not try and deposit siacoin sc funds into Poloniex. I linked my Poloniex account with my a3 back in January when I received the unit. There were 4 separate deposits made during the first 2 days, totaling 2,500 SC. Here's a screenshot I took this morning, still no coins even though siamining.com has it as completed as well as all other transactions that I since switched over to hitbtc. No issues whatsoever with Hitbtc. I sent Poloniex support a message about it on the 30th of January, giving them 2 days to complete the trx before opening a ticket. As of today Feb 13th 2018, I still have received no correspondacnce, and have no idea where my 2500 SC are as of right now.
