I'm not interested in retrieving the processing fees. I just want my bid back because I don't need the domain anymore. How is this done?

Nobody knows?

I registered an ENS domain a few weeks ago, but I would now like to un-register so that I get my ETH back. I don't seem to find any documentation on how to do this, and myetherwallet.com has no option for this, only for registering.. Can someone help me please? Is it possible?
Thank you!

I'm coming back just for another final question: To transfer from bitcoin to pivx I need an exchange? Or can I just send coins from one bitcoin address to a pivx address? Thank you!

Hello,

I have some ethereum in a wallet at bittrex and I'm trying to buy some PIVX, however the PIVX address seems to be in something other than hexa. For example, the eth address is 0xabc3a82747637e8093e25ab74101f5a..... and the pivx address is D8i9xg1GabVyZjUSdUXT5AXu6rUFF3BgPF (notice it has no 0x at the start, at least that's how it's displayed in bittrex. Also if I'm trying to transfer eth from my wallet, I get this message: "In the withdrawal address field, we only support hex addresses. DO NOT use direct iban, indirect iban, or unique userid. A proper hex address starts with "0x""

So, in this case, how can I buy some pivx? It's not possible to transfer from a ETH wallet to a PIVX wallet? I need to convert to something else first or how?

Thanks!
