The move may not attract foreign investors, but it will encourage some domestic entrepreneurs to try to make money.
If it were that friendly to the domestic entrepreneurs, I think Mining in Kenya or Most African Countries would be a thriving business by now, but it isn't. When they talk about crypto Mining, you will hear about Asia (Mostly China). Europe and North America. Africa and South America rarely come up in the mining conversations, probably because it's barely a business venture there due to;
1. High power prices
2. Very high taxes on mining equipment imports and that revenue ends up in corrupt individuals pockets
3. Instabilities in different regions
4. No wide spread knowledge about Bitcoin mining yet
