What happens to Bitcoin if our power grid goes out?
What happens to your bank account 401k and IRA if the grid goes down?
And FYI I own some Btc and Gold Silver and lead….
As mentioned previously the same thing that happens to your bank accounts, pensions, 401K, VISA CC, etc.. Only Bitcoin is better than those in that when a few Bitcoin "nodes" come back online with a generator/solar, etc. Bitcoin transactions can resume. Many thousands of nodes...each one have a complete record of all Bitcoin transactions since 2009...I am running a node at my house....I have got you covered! ;-)
BTW: if your 2nd Q is "what if the Internet goes down"...the Bitcoin network has been established on HAM radio and satellite.
