To whom it may concern:

I fully support a Bitcoin ETF. Blockchain technology has the potential to positively impact our economy thanks to its efficiency and near-limitless use cases. SEC approval and regulation would go a long way towards the legitimization of this new asset class and help cement the US's place in the world as a technological leader.

Best regards,
