I've got some ybc as well and that wallet maintenance has been like that for at least 7 or 8 weeks (probably even longer).
my understanding of seized coins or frozen wallets is that one's balance/coins are not even available for trading.
but, in this case, they are.

anyway,
can't really help you. just wanted to know what you meant by 'seized'.

don't know if I am going to sell my YBC today (with a loss of approx. 15%) or if I am going to wait for a miracle.
I've been patient for so long :-/
I asked support three times about the latest proceedings regarding the wallet maintenance and didn't get a satisfactory answer at all.
might just sell them and get my BTC out of cryptsy and forget about ybc (and cryptsy)
