Here's another issue:

If you want to see this in action, look here:

and keep clicking on "Previous output". You'll notice the staking amounts have been splitting in half after every stake.

Which means the amount of interest Neucoin is getting is slowing down. Every time this happens, their UTXO's get smaller and take longer to stake. Eventually they'll lose most of their compounding effect, and will have around 45 days of unclaimed interest in their mega account that will disappear as soon as they try to make a transfer from it. I tried to explain this to them in that thread, but it seems they can't quite grasp the concept.

Another sign that their technical team today isn't really up to the task.
