Not sure if someone posted this already - but there was just an announcement about a real estate development in Dubai that will be accepting bitcoins to purchase apartments (or condos or flats depending on where you live

)
Units start at 30 bitcoin
Do a simple search for ''bitcoin dubai real estate''.
This is definitely a sign of some mainstream usage
That's new to me , since i don't usually read news. Thank you for bringing it up. But i think its a big risk for the developer , but also a great way to use bitcoin, literally mainstream in these generation.
