Don't sell your real estate property for bitcoins.
 Bitcoin is very good, but real estate is very, very good. Having 2 or 3 homes is better than having a home and bitcoins.

Thorough the humanity history people have done this (sell the real estate property for money) and they were left with nothing in less than 10 years.

Bitcoin is like Gold and appreciating the Bitcoin value is like building a home. It is work every day for years.
If you sell your real estate property for bitcoins you will have to work twice once for that home (to build a new home) and once to appreciate the value of the bitcoin.
