Cryptocurrency investing through unregulated exchanges is risky for individual investors. Thus a regulated vehicle such as the Solid X Bitcoin Shares, backed by PHYSICAL BITCOIN, is the safest and most logical way for qualified individual investors to gain access to this new and developing asset class.

Thus I STRONGLY encourage the SEC to approve this ETF backed by physical bitcoin.

Thank you for considering my comments.
