You may need to consider investing in real estate than bitcoin.
Why would they?
You don't really own the property since you need to pay a myriad of taxes and you need to repair it; if the taxes are raised or if the interest rates go up, the price of "your" property is likely to go down; I am not even talking about a revolution or a natural disaster that will reduce the price tremendously
Don't really own the property? That's a negative oversimplification of real property rights.
Also, my last mortgage was LESS per month (including taxes and ins) than the going rate for rent in my area. Then I sold the house after three years of ownership and net profited 70k USD. That's net profit.
I'm sure you can find plenty of negative stories too, but to say you can't make money in real estate right now is patently false. It just takes a smart investment.
