you do not hold leveraged etf for longer than a few days.  you have ugaz and dgaz, both 3x leveraged, one longs one shorts.  what happens if you buy both? you don't get 0% return. in fact, you get -10% return if you hold both for 3 months.   no matter what happens, they both go down in long term.  call it leverage decay, beta slippage, contango, rollover, etc.  if you want to gamble that ng goes up within 3 days, go ahead. just be prepared for the worst cases like losing 15% in 3 days.  if you want to speculate the ng will recover in a year, buy natural gas industry etf http://www.ftportfolios.com/retail/etf/etfsummary.aspx?ticker=fcg
