Let's be rational here, why would SEC approve a Bitcoin ETF?

So, what are the good reasons why SEC would actually consider to approve such thing as a Bitcoin ETF?I mean, that would be an investment vehicle traded on the US that would be linked to a still obscure digital currency out of their span of control. Even worse, mostly controlled by chinese miners!Would SEC approve such a dangerous product, exposing US investors in this way? Does it make any sense?I witness a lot of speculation right now, but I'm afraid this might end ugly if/when people start realizing this might not actually be approved. via /r/Bitcoin http://bit.ly/2mmcftU
