But I don't think the internet apocalypse will do a huge damage to the banking system. because we can do banking things manually. because there is physical money we can touch. So I don't think this will have a huge impact on the dollar or physical currencies.
Transactions in fiat is heavily reliant on the internet. Majority of transactions today are made through credit cards, direct mobile transfers and USSD codes. If there was an internet black out the damage will be huge on the banking system.
Even the cash transfers are heavily funded by mobile banking to make the cash available at ATMs and POS stands.
Within a few days there will be such a crisis and more people will begin hoarding the available cash they have a hand.
However I want to know your idea of what will happen to the bitcoin network if the internet apocalypse happens. when we compare bitcoin to traditional currencies. Is this going to be the disadvantage?
It will certainly be a disadvantage. There has been some alternative means of transacting with Bitcoin that have been discussed but none on them can replace regular transfers using the internet to broadcast the transactions.
Maybe at such a time efforts to get an alternative will be intensified, but pending when that happens it will negatively affect price and possible halt all trades.
