Honestly, if they have a better electricity rate then it would have been awesome. Think about it this way, they have 16 cents for business and 20 cents for houses, if they dropped that down to half for business then they could get all the miners there and could make a lot more on income taxes as well. Don't get me wrong I am not saying give them the electricity for free, of course make them pay for it, but nobody will move to Elsalvador with a 16 cent cost, 10 cents or something would make it better. It is still profitable at 16 cents but doesn't worth to change your nation.
This is just the miner situation, you could still do an exchange or something else, crypto is growing so big that there are a million different stuff going on there. Which is why I personally believe that it is quite important to have a business in a nation that sees you as good business, instead of risky one.
