Is the price of BTCZ on different trading platforms different because the wallet can not be updated?
There is only one BTCz . No old chain. No wrong chain. There just isn't such a thing.
CCEX is a scam exchange with no user sign up. It was pretty much a fake front set up to charge listing fees including 4BTC from BTCz. The BTCz you see on CCEX is not BTCz it's some random thing they have with no miners or network support.
