They are functional but a lot of them are backlogged and due to this need time to figure out all the withdrawals and support tickets. You will have to get verified anywhere basically the only exchanges I know of that don't require verification are the smaller ones. Ie like Mercatox, Bitgrail, Etherdelta etc.
Some have simply cancelled all new registrations until further notice. Others simply don't respond to queries (waiting over 10 days).
I understand that there is clearly a backlog but I have business to do.....
I'll have a look at the smaller ones you mentioned. Have you experience of any of them? What are their rates like? Would you be uneasy in transacting a large amount through them?
