Its certainly interesting because it’s a daring project. They promise no taxes, but who will inhibit this city? Certainly not poor people, or even middle class. This will be a city only for privileged rich class, which would live in a tax free haven. It will not bring anything to Salvadors society which is mostly poor. I would rather see him spending this money to fix the living condition in his country.
Just wondering on how the government could run the economy since they offered that tax free haven? If majority of people will adopt bitcoin and the government cannot get a revenue out of it then maybe they are not on the right track? But anyways since they plan to have that for sure they have some ways to be earn from that implementation.
Also this is a good move by El Salvador since this could attract more bitcoin user and its adoption.
