Interesting! Using whiskey as an investment, these bottles really gain in value over time and to the correct buyer you could sell them for a lot...
But if whiskey is a huge market, there another alcoholic beverage that can be used as an investment, wine! There are bottles of wine that sell for hundreds of thousands of dollars and there are many bottles trapped in cellars gaining value right now.
Here in Venezuela, I think the dream of everyone who tries to get rich quickly is to own a liquor store! :') I'm always hearing about it. I hadn't understood their drives until I read this post today. It really seems profitable in many ways.
Wine is good also, but there are so many wineries and regions that you really need to know your craft if you are buying low for an investment.
