As far i know, we can make transaction using bitcoin without internet, we can using cointext. Our transaction just using text messaging but this service not all country and i am believe in near future, more country added in their service

Yes. Cointext enables people to send crypto with SMS messaging on even the most basic phones, enabling third world countries to easily access the blockchain world. If technologies such as this one, the satellites, and the mesh network antennas become largely used in the mainstream world, then Bitcoin and other cryptocurrencies would greatly defeat the purpose of Fiat currency. The huge advantage Fiat has, is that it can be used offline. Being able to transact offline with crypto was never possible, until now. All of this means that Bitcoin and other alts would rise to the level of Fiat in the future.

The best technology yet, is Blockstream's Satellite network, since it allows Bitcoin to reach areas no other transmission signal has been capable of before. Even cellular networks are not largely accessible to every region of the world. Which means, that using SMS to send/receive Bitcoin may not be the most viable alternative for offline transactions. On the other hand, Satellites can reach anywhere with the only downside that their signal would become disrupted by bad weather.

Nonetheless, with satellites, mesh network antennas (goTenna with Samourai Wallet), and Cointext (SMS messaging), it's now possible to send/receive Bitcoin transactions offline. With this, Bitcoin can reach the whole world, making crypto extremely popular like never before. Just my thoughts Grin
