El Salvador going to use Volcanic sources of energy to mine Bitcoins
Salvador is going to invite miners to mine there, not mine themselves! Big difference!
And the key for miners going there is the cost, green or dark, red or yellow the price per kWh is the one that matters.
If Salvador will not be able to offer energy cheaper than what others do, nobody will move there to mine, and the second problem is the amount of energy they have at their disposal, they claim they have 90MW, but that plant was in construction for years, it wasn't built yesterday and it's just surplus that will fed miners alone.
There is green energy everywhere, Italy has more geothermal energy than the entire potential Salvador has, but there are no giant mining farms there. California has the biggest geothermal powerplant in the world, with 1600MW, but look
where miners in the US are moving to, good old coal, and why ?? Marathon will pay $0.028/kWh for the energy, which is about a quarter of the average US domestic rate of around $0.11/kWh.
The price per kWh is all that matters, the gree stuff is propaganda.
Unless Salvador manages to keep it under 2 cents per kWh despite rise in consumption it will attract miners, if not, simple, no!
