What do you mean by they can use it when they go home? You can't use crypto that many places.
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.
