Recently we were visiting London. I had read somewhere that the UK authorities had banned BTC ATMs because, well, reasons. coinatmradar.com did (and still does) show some +/- 10 such BTMs in greater London. So, being the sort I am (I did not want to hang around my wife and her friend doing boring tourist stuff) went to check one out.
Well, it turns out that I found one that would sell me BTC without asking for ID or even an SMS by cellphone. Just put your money in, and get BTC out. Worked just fine.
BTM located in a market with an ethnic name close to the Angel subway station ("Northern Line").
When I travel to other countries, I like to buy BTC as a souvenir, smile. It also gets me to visit places I otherwise would likely not visit.
Very interesting.
Bear in mind re: SMS verification, that in the UK you can buy SIM cards without showing ID.
