Why buy silver or nat gas? Kick butt investment vehicles for your brokerage account

I'm not an investment advisor...

But why buy SLV for silver or UNG for nat gas?

Buy 3x SLV... USLV

or UGAZ for 3x nat gas.

You need to time these vehicles well but if you buy on major dips you can almost always get out even or up +15%-30% at a clip. I have been MAKING BANK over the last few months doubling my investment. GOOD LUCK!
