Being a leader and pioneer with this endeavour, I think it is just fair for them to take their time to prepare thoroughly for this.
It's not a matter of them taking their time for this, but they simply haven't had the regulatory approval they needed to actually launch next month. They might not even have it in January.
Them trying to work out things is just an excuse so that it seems like everything is all fine, while as I said before, no prior preparation is enough if there isn't the regulatory approval you need to actually launch.
The CFTC has been kind to Bitcoin with their CBOE and CME approvals, but they saw what happened afterwards. For us Bitcoiners it's a simple correction after a bull run, for non Bitcoiners it's manipulation.
