The future of bitcoin is still not a stable one,there’s a lot of controversies as to,as it has many regulation issues.Even the original founder of bitcoin,in fact, has left his position as it was headed in a direction that he did not intend(debatable).The average consumer is not yet comfortable with the idea,or understand,the concept of bitcoin or any cryptocurrency.
And it will never be stable. Bitcoin is an attractive investment vehicle because the price is always fluctuating and has a huge upside potential. The concept will be known to the population slowly but surely. It is still comparatively a new currency.
In my opinion,cryptocurrency will be used in the (far) future as a secure way to transfer money,if it is endorsed by certain regulatory body.It will largely remain to the discretion of the buyer/seller,how they would like to proceed with bitcoin,for the time being.
It is already being used as a currency system. However I understand that unclear regulatory framework is discouraging a lot of people to get into crypto currency. I am sure a lot more clarity will be available with time.
The first person to sell their home for bitcoin already happened in Alberta,Canada who sold his home for the equivalent of $405,000 worth of bitcoin(which was worth much less then),do keep in mind that this was like years ago when 1bitcoin was worth $70,whereas to now 1bitcoin is worth approx.$70,000.If cryptocurrency does not blow up in our face,then i think there would be a cryptocurrency for real estate,but it will be something other than bitcoin and something that a governing body would launch.
I know a similar story for ETH. A person sold his home to buy ETH at $3. He is a multi millionaire today. Some people have taken calculated risk and came out as a winner at the end. But the experience may not be same for everyone. So I would say it's a move where a lot of factors need to be considered.
I am not sure what do you mean by the crypto currency for real estate. But I can tell you that the market doesn't need another cryptocurrency specific to real estate.
