"Talk to your bank about physical banking." Is this person terminally online? Physical banking is always an option. If Trump pulls something radical, physically going to the bank won't change anything. Your money, unless it is dollars under your mattress, is always only a number on a computer even at a Credit Union where you can physically withdrawal money.
Get a landline phone? Landline Phones are routed through IP networks like cell phones. While there are some POTS still in service, you cannot order new POTS service. Nor does it offer any security over an IP phone. The government required landline phones to be monitored back in the 1990's. This isn't the 1960's.
" Everything will be routed through StarLink" StarLink is a satellite service. It is physically incapable of handling the global traffic going over fiber.
"Get a phone without StarLink." Although it's technically possible that StarLink could be used to spy on you, it's completely unnecessary when the cell service companies already provide everything to the government easier and cheaper than StarLink. StarLink is only one other group of frequencies of the dozens your phone already can use for local or foreign roaming.
You say the best option for storing money is cash under the mattress but I'm wondering what you think of cryptocurrencies in this case. I'm thinking that while keeping a flash drive with some Monero isnt physical, and requires internet to be used, it cant be taken or controlled by anyone other than yourself so it satisfies that at least. Also theoretically you could memorize the 25 word passcode that most wallets offer and store the money in your memory to some extent
Crypto is far worse than a bank or cash under the mattress. With a bank, it's insured and you have legal means of recovery if something goes wrong with the bank's systems or simple theft. With cash in the mattress, it's safe for any other than fire. But there's safs and safety deposit boxes for that.
Crypto is virtual Magic the Gathering cards. There is extreme volatility. You are still exposed to government changes. Tomorrow, Trump could declare Trumpcoin as legal for tax payments and Monero as illegal in the US. This would crash Monero's price. Flash is about as likely to fail as your mattress is to burn up in an accidental fire so there's no improvement in physical reliability. Bybit's cold storage was hacked and they lost $1.5 B.
That’s a good read with some good recommendations in it. Also the analysis of Elon’s intent to mimic WeChat seems correct. Thank you for sharing, are you the author by chance?
