The adoption of new technology is the foundation of our current upbringing in 2018. Younger CEOs of companies and personal investors are getting involved with the cryptocurrency world and want validation on this currency by a backed US government decision. Please accept this ETF for Bitcoin as it will help expand mass adoption of this upcoming technology to the world.

Thank you.
