There are people that have done this. They sold their properties for money. They were left with nothing in 20 years after they sold their properties.  

A property is something sacred, it is a lifetime work, you can not sell a property for some bitcoins, saying that the bitcoin value will appreciate. There is no person in this world that can say what the future will give. There is no person in this world that can say, tomorrow this and this will happen every minute.

We can say that the day of tomorrow will be approximately as today, maybe somewhat brighter maybe somewhat worse, but we can not say precisely what will happen in 3 years from now.  

Thus my advice is not to sell.
