Respectable Members of the SEC:
I hereby wish to express my support for the VanEck SolidX Bitcoin backed ETF.

My motivation is based on the protection of the investors who have given their vote to this innovative financial asset. The approval of this ETF will motivate the adoption reducing concentration and speeding up the release of its great potential.

I am confident that the SEC will make the best decision for the financial system and its investors, as evidenced by its open and receptive approach during the evaluation process of the VanEck SolidX Bitcoin backed ETF proposal.

Thank you and good luck
