Exchange 75 NFD to 3 HZ successfully, in the same account, 3 million HZ exchange blocked, WHY?
Simple answer: you're now waiting in line, as am I. The HZ devs decided to issue the HZ slowly, so as not to flood the market and provoke dumping. Look at your Recent Transactions: if you're in the same boat that I am, you're getting a trickle of HZ every day.
If not, you're still in the queue.
This is correct.
