Eli5: Exactly how is the blockstream satellite thing useful? I understand that you can synchronize a full node from the satellite and while admittedly that is cool as fuck. It doesn't seem to have any use because you can't send #Bitcoin transactions out unless you have an internet connection or you sign a transaction and then put it on a flash drive or something and take it to where you do have internet. Am I missing something here. The other use case I've heard of is remote mining facilities. But even then, they would have to broadcast their mined blocks over a cellular connection or something. Unless the cellular network is extremely expensive, you could just synchronize your node over that instead of dealing with the satellite.
