lost count. What I do now is tip staff, let them nag the merchant. The area I live has many backpackers, once they hear they can use it when they go 'home' they want it. Much easier.
yes. when merchants see staff get tipped it gets them curious especially with handcash or cointext. I've been surprised at how many people 'know' about crypto &have always wanted some.
varies, French girl is travelling through Asia on her way back2 FR, Bali has a few places that accept BCH. Another mentioned some cafes in her town accept it, XHousemate used it in US.
he reluctantly used my Lamassu when I was setting it up at home, "put in $20" (BTC was $100 at the time). When he returned from US.. "thanks, that came in handy."
he used in a taxi when he didn't have US$, somebody else in the taxi happily took his BTC and paid the driver I give up 'knowing' how it will be used by people.
responses have surprised me, particularly young girls.. one "oh yeah my friend has been trading for a while, she loves it" Me, "well, you can show her this new wallet" *B I G* SMILE.
