I should also mention another reason why banning cryptocurrency is not like banning encryption. The only thing that encryption actually needs to function is two people, and the encryption algorithm itself. If any two parties agree on the algorithm and a set of keys then they can create a secure communication channel; it doesn't even need to be over the internet, you can communicate securely by copying the message onto a flash drive and sending it via carrier pigeon, or just writing the bits down on a piece of paper and putting in a wine bottle and tossing it in the river. Now, those methods definitely may not be reliable, but they are theoretically secure if the message is encrypted. Crypto on the other hand, requires a running network of many publicly identifiable participants to function. The blockchain code by itself does nothing; this network only functions if it has a critical mass of miners to run the network and a critical mass of buyers to pump up the price of the token. Without those things, the token becomes insecure and worthless and can't be used. So inherently, crypto will always be an easy target for attackers, will always be vulnerable to getting shut down by governments, and will always be manipulated by ponzi schemers looking to make a quick buck. This is a fundamental design property of the system, you can't fix it by adding some more code to it. It's also the same reason why all the marketing around it is a lie. Cryptocurrency is terrible as a currency and terrible as an investment, and just all around terrible.
