Maybe she was lucky that her country and the countries she was travelling to were actually receiving the payments in cryptocurrencies.
If one would travel in a developing country like India , one would only be able to maybe buy a coffee using it , same is the condition with ukraine.

You are wrong about India as their is no shop or place where you can do cryptocurrency transaction apart from converting to fiat currency. Even now India have banned the cryptocurrency usage so it is not possible to use cryptocurrency in Asian country's. I think she has mostly travelled in America and Europe country where only it is possible to do anything through crypto currency.
