When i was saying he should have cash it doesn't mean literal paper currency.

Crypto currencies.  

I hope you get a good exchange rate with the currency exchange. 

Long term I can see Milwaukee home prices creek up to the national average, which probably means they will double over the next 10 years, partially fueled also by inflation (devaluation of currency).You could try and BRRR on the fringes of that gentrification, which should work in theory, but you already need a fair amount of comps over 200k for it to work and a "good neighborhood feel" - I have not seen it done yet and the risk is of course that you don't see the same rate of value gain as you see in desirable communities..

Don't forget currency exchange and FIRPTA risks. 

Since it's major world currency, every living organism in the world needs USD3.

Blockchain is a technology which crypto currencies are based on.

I am looking for software that can handle Canadian and US currency, RRSPS, RESPS and the provincial rules for each province.
