So Nutbox has had a massive loss in delegation, but will people return? Possibly, they need to get the rate of return up, and people will come back. Seems to be why some people left, while others left over the hack.
One thing everyone seems to be forgetting is that other projects have had hacks, and went on to be successful. Leo is a example. One of their pools was drained the same way. High yields and time will cause people forgive or to forget.
But this might have been the shake out needed to get yields up again.
