We do live and exist in a fiat currency debt bubble and part of existing in a fiat currency debt bubble is the reality that booms and busts are perfunctory per design of the system.  

That being said, the majority of my assets are in real estate, but I also contribute to a Roth IRA, S&P Fund, hold shares in Fortune 500 stocks, and recently have invested in crypto currency.

Stocks and Crypto are just as likely, if not more, to “crash” in comparison to real estate.

I’ve invested a little money into some stocks and another bit into cryptos since that doesn’t require me to be that invested.

Long story short, I got really lucky with some crypto investments and will have somewhere in the vicinity of 120-160k to invest in real estate next year.  

US currency downfall as the fiat currency.  

There's also the possibility, and I know many people think it's unimaginable right now, is that the developed world total debt will become so huge that the powers that be decide to wipe everyone's slate clear, and declare a single, new currency.

That extra money is allotted to other investments whether it be more real estate, bonds, crypto, stocks, etc..

There are places to park your money in crypto and earn 8-12% but when you cash out, you'll have to pay gains taxes on it and since you're looking at short term, I don't think it would be worth it.Keep doing what you're doing.I would stay the course, find ways to cut expenses even more.

Currency may become irrelevant.
