Long live the Queen.

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!
My grandad has been quizzing me about Bitcoin as he thinks they will be great for travelling if more ATM's pop up. He gets very disgruntled with currency exchanges and banks, he said the idea of having bitcoins and swapping them for local currencies with people / ATM's seems a fantastic idea.
So there is yet hope that some of the older generations will see their utility, although my grandad is a little clued up when it comes to these things as he is a big advocate of gold over cash.
