Depends what you invest in - investing in some stock that returns 8% and then selling it for a cash profit isn't, which is what most people do when they turn a profit in stocks. Keeping stocks in precious metals however...

Gambling is technically another way..

Keeping precious metals> keeping "stocks" in them.

The worst option...

Another way to combat inflation is to own resources with a physical value like a house and food/water. Then you don't need paper currency

Tell that to the millionaire professional poker players..

Correct but if you use the right traders then the stocks are literally put in a vault. A lot of them lease the gold to banks though

Poker at that level is not gambling

ask the guys who blow their weekly pay-check every week...

I agree.. Im just using the word "gambling" as a broad term.. That's irrelevant to the point I was making tho..
