Dear SEC staff,

I will keep this short and concise as surely you must be overwhelmed by the huge inflow of requests on this matter.

I urge you to thoroughly analyze the amazing advancements and breakthroughs that blockchain in general, and bitcoin in particular, will enable all over the world. By allowing BTC ETF's, BTC's value will surely rise and the world will finally and unequivocally know its true potential - unfortunately the vast majority of people will only look at superficial characteristics, namely value, to further study something.

This is, in short, a great opportunity to expand the ramifications of a technology that enables, above anything else, trust. Please do not underestimate the implications of the task at hand.

Yours sincerely,

João Silva Leal
