Personally I have invested in cryptocurrencies but due to the current market, there is no sign that I will profit any time soon, so I guess the result of the investment remains unknown. Although I still have steady income from my job, uncertainties will not diminish as I hope for a stable feed for my family and for savings as much as possible. What is your situation in your country ? Are you going to experience some economic turmoil as well ? Please let me know.
Do you think that price is going to fall down? If yes, then you can still profit via Margin trading if you short sell Bitcoin or other coins.
Real estate is collapsing and even the rich people have no options to invest.
If someone can think of an investment plan in the middle of a recession, it means that he is able to maintain a stable financial condition, while in the midst of a "collapse" the real estate business is a good investment opportunity to start in that sector. Why "no choice"? Unless you state where you're from, some countries are simply not suitable for real estate business in various global economic situations.
He probably says that real estate prices are so increasing that even rich people can't afford them. I don't think that real estate is a good option when its price is gone too far where a lot of people can't afford it. Market crash happens and real estate market will crash too, it won't grow forever.
