I'm not quite to the point of making gold, rations (and ammo) a major part of my investment strategy.Alcohol and cigarettes are also good trade commodities if the currency becomes worthless.

A wire can be used but wire fraud is a huge issue so you'll want wire instructions to be sent directly to the user who should be instructed to verify the instructions before executing the wire.Don't accept/provide currency. 

I have about another 10k in investments , 5.5k in my Roth IRA , and 3.5k in my Robinhood account as well as 1k in crypto currency

Healthcare systems are starting to get more stocked on supplies and are in a better place to handle more of a surge.  26 million Americans unemployed already, supply chains and businesses failing left and right, currency debasement at unprecedented levels etc. is going to have so many more ramifications in years to come that I think we really need to start opening things back up again. 

I decided (thankfully) to move it out of crypto currency and into my specialty, rentals.

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.

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.

Currency may become irrelevant.
