It is possible, but many countries already legalize crypto. If in a country the government prohibits the developers, then they can move to another country that is crypto legal there. For example like Binance ever did, they move from China to another country that accepts crypto projects/companies. So, there is still a chance for the developers to create new crypto coins. We don't need to worry so much.
It is possible, but in the other sense this is to maintain those new projects that don't have any other thing to do but to scam people. But if it's a legit company that they've stopped.
That's what they're going to do and fly around to nearby country where they're allowed to make it. But I think that's too much for them if they're just a new coin and starting out.
