Would it be possible for a small nation to fork bitcoin, in an effort to recreate the early glory days of mining (low difficulty era) for its residents.
Which could in turn produce prosperity and wealth, somewhat out of thin air, in a deflationary capacity.
Bitcoin is open-source software using an MIT License, which means you can freely copy, distribute, modify and even sell copies of this software. As far as I am concerned, the only condition for copying such software is that you must include the MIT copyright notice. In other words, El Salvador absolutely can modify Bitcoin software and create its own version of Bitcoin (fork). As for recreating "the glory days of low mining difficulty," I think it is only possible if the fork is highly unsuccessful because otherwise, existing bitcoin miners will use part of their equipment for mining this state-sponsored fork, thereby automatically increasing the difficulty of mining. But creating or issuing your own money doesn't magically make you prosperous or wealthy because first, you need to convince your own people that this money is good for them (which, of course, a dictator can achieve via violence, aggression, torture, and propaganda), and second, you need to convince your neighbors, your enemies and all other countries that El Salvador's bitcoin is good enough to replace the dollar and other currencies when conducting trades between countries.
Perhaps it is possible for small nations like El Salvador to recreate and even build upon this success.
Bitcoin Cash is a scam coin created to siphon off money from naive investors; and since its creation, it has only been dropping in price against bitcoin without the hope of ever catching up.
