Any government can shut down the internet? Really? So far only China has done that and only partially. How realistic do you think it is that the US says one day “Sorry, Internet is closed, we’re back to the 80s”
An if they do that, people will emigrate. Or maybe you are suggesting that all countries in the world agree on shutting down the internet. Again, totally unrealistic.
So far no government has made it illegal, not even China. They try to slow down adoption so they have time to react, but it is an asset like real estate or gold and is very difficult and unconstitutional to ban it.
About CBDCs, yes, they are coming and yes, governments will try to push them hard, but not many people are going to use a currency that can be deleted from your wallet remotely, that will trace every single transaction you make and that can be use as an Orwellian tool for controlling the population. China would love that, but Chinese people won’t, that’s why they are stocking up on BTC despite all the difficulties.
The US will create a digital dollar but it will be worthless. Fiat money is a dangerous ponzi scheme and a bubble that is about to explode. They just printed another 8 trillion, don’t you think that’s dangerous?. Get some exposure to real assets (real estate, gold, Bitcoin) or you’ll have a hard time surviving the next few years.
