No matter how much we want, but the states will periodically pay attention to the energy consumption during mining and circulation of cryptocurrencies, because for the states these are actually unnecessary financial structures.

With regard to bitcoin, in this regard, there are already periodic threats to ban it precisely because of its relatively large energy consumption, and you need to be prepared for this.
