Sorry to hear about your nephew.
PolyCub has been pretty insane to say the least. Personally I didn't use the right strategy with it so I'm going to be farming on it rotating my strategy overtime. It took my BiSwap play six months to really bang so we will see if strategically I can make this make sense way quicker.
Hopefully the marketing push will help and I don't know if PolyCub is going to end up showing up on other farms as well.
