I agree on the above post it's not safe to buy gas with while online in your phone when paying crypto on the gas station.
Maybe if they can develop a crypto that can be send offline maybe it will be fine but if it needs internet it is not safe.
Remember gas station always have caution and phone should be always in airplain mode when using it near gas station.
I think become dreaming in my sleep well because my country look disagree bitcoin become legal transaction currency payment, I support for every country have possibility using bitcoin as legal currency payment like using crypto at gas station where payment more faster than cash money or other fiat currency, but how safety if using crypto as payment transaction at gas station.
