If you think this is a fraud then doesn't it make sense for you to sell your BTCZ and leave?
Of course if you can't sell them like you claim, I will be willing to buy them from you...at a much lower price of course since this is such a fraud.
I do not understand developers
How can I propose to choose between BTC-Alpha and Cryptopia.co.nz

that's bullshit!
it seems to me that this is a fraud.
because the choice is obvious, it's Cryptopia.co.nz!
you know why the price has risen? because coins can not be sold on exchanges, they do not work.
and the developers are proposing another shit exchange BTC-Alpha)))
there is some kind of fraud
