I'm from Nigeria and as you all know, Nigeria is a developing country and when it comes to internet connections we're not there yet. I live in the city area but travelled to my village few days ago for an occasions. On the way, I got a call from a friend requesting to buy $550 worth of bitcoin, I tried sending the coins to his wallet (he's a regular buying so I already have his wallet) but the transaction refused to go through because their was no internet connection. When I finally got to my village the transaction went successfully because we had internet.
After this experience I thought about other remote villages in Nigeria and African countries that don't have the Internet 24hours if they were to use Bitcoin (cryptocurrency in general) for day to day transaction can this be done without the internet?
I tried searching the web but couldn't find any post that gives me a satisfying answer, so decided to contact forum user.

There is way to transfer bitcoin without the internet, using paper wallet. But, in that way, it will just take the transaction longer. What if your transaction is across the globe? Who would want to carry a sealed paper on a plane and to a certain person? It will just take longer. That is why there is internet, it will make the transaction faster.
