From the discussion above it means I cant sell HAT o any other exchange. Because right now I have the new Hat and not the old anymore.
Yeah, the team has payed for listing on some other exchanges, but they (the exchanges) are not answering their support tickets. That's why the only exchange that has new HAT tokens listed is Idex which is under maintenance for another 2 hours. Then everyone will be able to trade HAT tokens again.
How do we Stake are HAT's???
There's a guide on the Hawala's website. Check it out. It's not that hard. I must warn you that today there was some issues with MyEtherWallet. Some people said that it was hacked so check if it's OK to use it to send HAT tokens.
