Thanks again chaps. I feel a bit of a muppet but kind of went along with it as this is all new to me.  It just didn't seem right though especially when they wanted money from me.  No harm done this time except for a few wasted hours but it's been an education.  I can see how people could fall for this!

Much appreciated.

Ok thanks guys, yes it all seems a bit too good to be true. He claims that he has reached his maximum monthly withdrawal limit from the site so can only transfer internally.
He was also willing to transfer the 1.62 bitcoin before I transfer the two domains (we made a deal for a second one which he wanted too!)

Yes thanks for that I had already googled them and got nothing and the domain was only registered this year but they are registered at companies house.

Thanks for confirming what I was thinking.

Cheers

Hopefully some of you experts might be able to help me.
Somebody has paid me for a domain name which I own (haven't transferred yet). They said they could only pay me in bitcoin on cryptcarbon.com
The payment is there but is the site genuine?
When I try to make a withdrawal to a Kraken wallet it says I have to send 0.02 bitcoin from the Kraken wallet to verify my address with them before I can make a withdrawal.

Is this a con or are they genuinely just wanting to verify the wallet address?
Please help, many thanks.
