But seriously, the continual expansion of these ATMs as well as merchants who accept BTC tells me we're smoothly mainstreaming ourselves while making sure all of the tools are in place for when the moonshot comes and the media and subsequently, the public writ large, is ready to hop aboard.
it is not yet mainsteaming as it could be and perhaps it will never go totally mainstream. As I cannot imagine my grandma using Bitcoins. And this is what indeed mainstream would mean - bitcoin for everyone

But indeed it is spreading widely and it is very good!
