Don't send coins from Bittrex to Startjoin. Mine didn't get there twice. Yes, it was 2.0 coins.
And also, yesterday I sent some 2.0 startcoins to my wallet on my computer, they came fine but today nothing after hours. The address is the same, also same address is not seen anymore on the explorer. I mean WTF.
This is alarming. Can you confirm that this is just happening to you on Bittrex? Are you definitely sending to the correct address? We'll try and rectify this with them
