Well, just did a quick bit of research, approximately 5 million yanks visit the UK in a year. Approximately 22% of adult Americans own btc. Summising that the visiting Americans are roughly 50% adult and roughly a fifth own Bitcoin, that would be 500k btc visitors. Hopefully they are all spenders and not Saylorites! Obviously I'm making generalisations Raj, I actually reckon the number is way lower but as I said, I love your optimism
