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.
With my existence and involvement to Bitcoin. I don't see any controversy that it has got aside from the foundation where it's being used from the other side, the illegal ones but cash is also used for that right? The regulations are normal because it's not centralized and about satoshi's disappearance, he's been out for so long and everything is handled by the core devs now that are in charged of it and the market relies wholly to us, the community and the institutions that are in.
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.
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.
There is no need for a crypto to be used for real estate, there is so much crypto now and Bitcoin is more than enough for that use.
