I don't have much experience to comment about Nubits but there were other attempts in the past from altcoins that claimed to be able to deal with cryptocoins volatility using bots and failed big time. If I remember correctly it was aircoin? Maybe this is something completely different but any attempt to control POW cryptocurrencies volatility with trading bots doesn't end good.
Again maybe I am wrong and this is something completely different. In any case even if I wanted to learn and invest in it there is no way I would sell my BTSX for anything else.. Maybe PPC go to $3-$5 but eventually the dump is very likely to happen very fast..
Be carefull. This might be a good oportunity for PPC holders to finally get out of their long term holdings...
Other than that PPC - XPM will always be in my hart and I have very much respect for their community. They were the only coins that I got involved and didn't experience any dumping for a long time..
