I'd like to see bitcoin to make a serious contribution to 'international development' (though I don't really like that term). An international currency has a real potential for alternative economics in places on the periphery of the capitalist economy.

Also, in relation to the hue use of resources, it occurred to me last night that mining rigs could be used as 'dump loads' in renewable energy installations. I have a bit of experience of working with wind turbines, and there is often a need in small scale installations to have somewhere to put energy when there is too much to use or store. With wind turbines, this just needs to be a windy day.

Mining rigs could automatically turn on when the wind is blowing and all your batteries are full.
