I do not know what solutions you are talking about if the use of cryptocurrencies will face criminal liability. Half of the users will simply get scared of responsibility and stop using cryptocurrencies. In my opinion, the ban will allow only anonymous cryptocurrencies and solutions allowing to mask transactions to develop, which is a rather small part of the cryptocurrency world.
If users are shy and do not want to fight those who are trying to prohibit something for them, then so be it. In my opinion, cryptocurrencies are created for free people. If these people are enslaved, then they first need to regain their freedom, and then engage in the economy. Thinking that you can "be an economically free crypto user" without being politically free is a big mistake.
