On one hand, the 'digital gold' aspect of bitcoin make it attractive for countries that want access to a non-US-dollar currency. However, it seems like the most sane version of such a system would basically use a private blockchain (or even a basic centralized tabulation service) run by the central bank. Having your central bank run a centralized system through bitcoin isn't much different than running a centralized system through some other currency. On the other hand, the power requirements of Bitcoin seem like they make it a very poor choice - both from an ethical point of view and a practical point of view. In the same way that using a foreign currency exposes you to the ups and downs of that currency, El Salvador now has to deal with the operational realities of bitcoin. This seems potentially worse than simply adopting another fiat currency because you've handed over control of how transactions work.
