There is all kinds of other egregious waste (electrical and otherwise) going on in the world, how is this any worse than say millions of computer's online/burning power to play DoTA for instance (sorry MOBA fans, nothing personal. using it bc it has an enormous player base). It's a weird comparison but it gets the point across.
Plus, relatively speaking.. an entire year to power the country of Ecuador is the same amount of energy it takes to power the Bitcoin blockchain for a year doesn't seem that "wasteful" considering how many lives Bitcoin has changed & the miracle of being able to send up to $x,xxx,xxx USD (or any other currency) around the world, confirmed in less than 10 minutes for a paltry fee of ~$5.
I'm not sure why but there is a clear bias on HN regarding most Bitcoin articles.
This is just my opinion; take it with a grain of salt.
