The lots are called "currency" land, investors in a 1031 exchange use them to balance a trade. 

I spent a good 2-3 years studying and trading stock options and then on the forex market.

I want to be a Real Estate investor, invest in stocks and/or forex.

It's a little tougher right now because the US dollar is strong compared to other currencies so you will find less small to medium institutions looking to invest in the US.

Next recession will be a currency crisis.

If it's buy and hold, currency flutuation don't matter that much...who knows our dollar might be back at $.61 in 10 years and then I'll be glad I bought when I did...

There may be a limited time to offer informed commentary on landlording.For example, it is hard to have  the capital or interest when too young and challenging to have the interest, energy and currency to comment when too old....When I hit ten years of active, hands on landlording, I had all types of tenants, several types of properties and transactions, then I began to share, knowing in another ten years or so I might not have the energy to comment or even  be on the way out (be it selling, owner financing, or farming out management). 

Hunkered down for 6 months and with some savvy investments in crypto-currency I was able to nearly triple my meager remaining investment fund from $27,000 to $80,000.

You have economic issues in foreign countries with currency, civil unrest,etc.If you did do it I would think it is a very small part of your overall portfolio.

Cash to me is  dead presidents , us currency , the green stuff .
