The real estate market seems to be very strong, but now it has reached the end, and there are very few countries that can invest in real estate. They are some new economies, and they belong to third world countries. These countries have certain profits in their housing prices. But I think the cryptocurrency market is more profitable, but both investments are risky.
If the guy lives in the country where the economy is poor, probably, it will be good for him to invest money in real estate abroad, in Spain, for instance. Cryptocurrencies are not stable still.
