In countries where crypto is "banned" (illegal for mainstream use), do you think people will still use it? In such an scenario, it's possible on-chain criminal activity (mainly money laundering, terrorist financing, etc) will rise. To prevent detection, it's likely both criminals and average people will use a privacy-oriented coin such as Monero or Zcash. Bitcoin will be the least used cryptocurrency due to its transparent design. But I could be wrong.
What do you think? Will people still use crypto in a country where it's prohibited to do so? Or will they be afraid? What if all of the world's countries turn against crypto (which is very unlikely atm)? Will market prices go all the way to $0?
Your input will be greatly appreciated. Thanks in advance.

When we do speak about chances and probabilities then we can definitely say that it wont go down to 0%, on which means that there's always the chance for it to happen. We do know that Bitcoin is pseudonymous on which when it comes to tracing up transactions then everything could really be that seen when we do speak about trails and thats why if people wanted to have that anonymity then this is the time that they do need up to make use of mixers on which this is the main reason on why these services are being banned because it was indeed the perfect tool when it comes on full anonymity of your coins or trying to mix up your coins to avoid that tracing. For Monero and Zcash then we can say that these are true anonymous coins on which you can make use of and if ever that the world will be that strict when it comes to legal compliance and become that too tight then there might be a chance that majority of the people here on crypto space might consider out into those assets on which can be able to provide that full anonymity and thats why we cant be able to say that there's no chance for it not to happen.
