A lot of people think crypto is the future of money. It is totally dependent on the internet and governments control the internet. In the past, desperate governments have done far worse things than turn off the internet. The crypto bubble is much larger than the dot com bubble. Some form of crypto may indeed survive and thrive in the future. Right now I think the risks are huge.
If you see a future where governments including ours just turns off the internet, then no point in investing in anything at all. Everything will tank. Might as well just build a bunker and stock on ammo and canned food.
Now assuming we don't live in that future where the internet is just turned off entirely, many cryptos can never be shut down as long as there is internet, no matter what government do. Bitcoin is designed to specifically withstand that. Sure you probably will have a hard time converting your Bitcoin to USD, but at some point in the adoption in curve, you won't even need to. This is all worst case scenario.
What we are seeing is the opposite. The crypto community has already started to infect the structure of governmrnt. Many elected officials are out right fighting to legitimize crypto. Hundreds of billions of dollars by top companies are already invested in the space and trillions are coming in.
When big institutions get into something, you better believe they will buy the politicians to protect it. Game theory at its finest.
