"Bitcoin doesn't exist. Nowhere on the #Bitcoin network, on the Bitcoin blockchain, in the Bitcoin system, is there such a unit as a Bitcoin. Everything is Satoshis. A Satoshi is the smallest unit, but it's also the only unit that actually exists. Everything in the system is measured in Satoshi."
- Andreas M. Antonopoulos
If you want to learn about #Bitcoin in a course-style setting, this is for you.
It's an absolute basics walk-through presented by Andreas M. Antonopoulos.
This 90 minute session, presented August 28th 2019, is designed to prepare you to study for and take the Certified Bitcoin Professional Exam (CBP). For those new to the industry, this will be your introductory course to blockchain related topics. You’ll then attend other sessions to learn more and reinforce the topics covered here.
You’ll learn about:
• The history of money, bitcoin, and how the price of bitcoin is derived.
• Basic cryptographic terms, hash functions, encryption, and digital signatures.
• Bitcoin Basics, including addresses and keys, transactions, the blockchain, bitcoin as a unit (e.g. millibt, satoshi), ways to earn, buy, sell, and store bitcoin, blockchain explorers and Unspent Transaction Outputs (UTXO).
• Bitcoin wallets, specifically: wallet types (hot/cold, paper, hardware, multi-sig, etc) bitcoin clients, and wallet backup/recovery.
• Bitcoin commerce, including how to accept bitcoin for products and services.
An absolute blast to dance to!

Layer 1 (L1) is the Blockchain ledger.

Is your doubt that all Americans won’t be able to use L1 or L2?
Do you mean all Americans using Bitcoin L1 or L2?
I remember watching this 2015 #Bitcoin lecture from Andreas M. Antonopoulos years ago. Excellent then and excellent now!

The listener really gotta want that Kung-fu level of training, depth, and history to upgrade their brain’s synaptic connections.
Someone’s first gotta have a reason that they wanna learn all that Kung-fu.
Find their reason.

“This isn’t a Libertarian currency any more than it’s a Communist currency. It’s a currency.
It’s a neutral currency. And neutrality is *the* most important principle in #Bitcoin.”

This is a good article. It doesn’t cover what would happen in a time of war specifically, but I believe it answers your question about “how” to use #Bitcoin without Internet. Although, if there’s no electricity then nobody’s using #BTC.
“…providing fellow Africans easy access to payments. He has developed a non-custodial digital wallet that allows people to send and receive bitcoin (BTC) without a smartphone or Internet connection.”
