I'm 68 and "retired", so do not want to commit to a BUSINESS and am not sure RE can be done as a "hobby" with great success.At present I trade currencies and options, but that is capital intensive and inconsistent income-wise.

Also seems smart to have an income source from another country as a hedge to currency fluctuations.Anyone out there feel different?

Now concerning market risk of a deployment, natural disaster, collapse of the currency or running out of oil or anything.  

If cryptocurrency is just another currency, then accepting it is no different than, say, accepting Euros, Canadian Dollars or British Pounds for your vacation rental then converting to USD.

I know it can be done because I've sat on google translate to annotate German tax returns into English, along with past-dated USD currency conversions to get a loan through, but yeah this is one where you need to shop primarily the competence of the lender, and shop it hard.

Hi DonaldInvesting overseas is a better way to expand your business.Things to consider:1) You must do extensive research on the country you would like to invest. 2)Know the legal, tax, insurance, currency exchange, tranfer taxes issues3)Don't assume that markets with low debt ratio are good for investment4)Work with Certified International Property Specialist(CIPS), TRC's(Transnational Referral Certified Agents), ICREA or FIABCI members to help you find International properties and provide you knowledge of the particular country and market.Dubai was great for flips, but not anymore.

Currency risk, the chance of being sued, finding a good team (especially a good property manager), not knowing the market in terms of good areas/streets to purchase within, having to rely on others people’s opinions to a certain degree (e.g real estate agents), and the general risk of distance – if something goes seriously wrong, not being able to be there in times of need.

Each state would have build its own military, its own currency, its own FBI, CIA, white house staff..redundancy and waste! 

You may have a currency risk though.

Canadians with their exchange rates on currency have cooled off some buying in the U.S. but other countries have heated up investing here.Lot of people in CA are willing to pay low caps because simply they do not need the money.
