I just want to say to please approve this ETF. Blockchain technology is clearly a beneficial addition to our world and by hindering its growth you are not helping us advance as a race. Digital currency eventually will be the way of the world, and whether it’s USD or some other cryptocurrency who wins and becomes the most useful, the competition between the two will give us the best possible outcome.

Thank you for listening to me.
