I am convinced that the next 40 years will look nothing like the last 40 years. As I lay out my investment options, I am analyzing them for future viability.

I think the modern man needs to consider the fact that fiat $$ may not work on a 10 year scale. I have a fund investment portfolio, but my gut tells me that things will get weird in that time period.

Here's what comes to mind:

Buy and hold:

Property: I owned a single family, but there was no money in it. Sold it for a small gain. Cleared maybe $250 a month, but periodic $1000 maintenance made this a razor-thin margin. I'm looking into 10+ unit low-income. It seems like risk doesn't need to rise with units.

Land:I'm exploring this now. Acreage, water rights, elevation. What kind of climate or demographic changes will drive value?

REIT's: I live in an area that is exploding, so I'm looking for a local REIT with some serious growth potential. I'm not an accredited investor, but I'd love to be able to directly fund a small property flipper. How can I accomplish that?

Commodities: I keep physical metals. I know there is manipulation here, including off-the-books reserves, but metals have been fungible since the dawn of civilization. I see this as my hedge against a SHTF scenario.

Short Term Play:

Bitcoin: I get a lot of shit for this, but I made a high five figures play in 2014/15. Any intelligent man should have a hundred $ worth of bitcoin or altcoin as a lottery ticket.

Futures Trading: My next endeavor. Looking for a basic strategy to keep the time commitment low.

Forex: Seems rigged. After the Nordic shit last year, institutional players seem to own this space. Curious for other takes.

General thoughts on intelligent investing for the modern man. What am I not considering?
