From Dan's original post:

Prediction for NuBits
The NuBits Ponzi scheme will eventually collapse unless the Bitcoin price can recover before there is a run on NuBits. It will probably continue to maintain a strong peg right up until the day it collapses. When it does collapse it will be sudden and the NuBit holder will get nothing.

It would be interesting to hear from @dan if his original thinking is one of the scenarios that is currently playing out now. Although I'd very much caution that it's done in the spirit of understanding and learning from failure - and not as 'I told you so'.
