3rd party? Can you tell what is that? Bitcoin is useless without internet.
Even they can send this possibly without internet, how will they able to use it without an active data connection?
the only thing that I can think of which works with his idea of using bitcoin without internet is to buy bitcoin in form of a paper wallet or physical coins and trade it that way but when you think about it really bitcoin without internet is meaningless and any method that you come up with is also pointless and a lot more hassle than using it like a normal human being with internet !
Yes or maybe buying a hardware wallet which has bitcoin loaded.
But like I said even that is possible, it's really useless since what is the use of having bitcoin if there's no internet around. Just to wait for price increase? Hmm not a good idea in my case since Im doing something to my coins whenever there is a large price movement increase.
