I understand that Bittrex updated their FAQ last week stating that you can swap your ERC20 QTUM coins for the new ones once their main net went live and you have until October 4 to do so.
They also said that they would cease QTUM trading on Bittrex until they were satisfied with the migration or something...
I noticed that QTUM is being traded already right now - so if I were to trade for QTUM right now, are they the new coins or the older ERC20 ones?
Qtum is not an erc20 token but qtum already run on its blockchain, as far as i know the qtum was building its own blockchain rather than use the other platform as the main platform to be their main system.
You can try to use the qtum blockchain too. It's a new coin with new blockchain system.
