Dear SEC members,

I strongly agree that a Bitcoin ETF will be beneficial for traditional markets and crypto currency markets. By allowing traditional investors to access a more technical asset class without the knowledge of managing and maintaining said assets, you eliminate a large amount of fear surrounding digital information in general. The general investor wants exposure to this newly budding asset class, but we all know it can be difficult to grasp complicated technological advancements.

Sincerely,
Christopher J DiRubio
