They are BOTH correct.Huge daily % volitility with HNU. If you good, you can trade it and make huge amount of money. HNU is for Trading not long term hold.
You have to be good.... otherwise you will lose your shirt. The odds are against you. Just look at the long term chart. DOWN DOWN DOWN DOWN..... Consolidation after Consolidation after Consolidation. Just pull up 10 year 20 year charts.... that should make you think twice
All just my opinion/view/thinking.......
