Well, it would depend greatly on which real estate you mean. There are empty cities in China which testify that real estate can, in fact, be very risky, but most real estate is not like that.

Lots of other places where it is certainly not safe, but in the end you can at least use it as a place to live (unlike the Chinese ghost cities), whereas Bitcoin does not have any intrinsic use (even T-bills can be used to pay government debt such as taxes).
