Sirs,
Referencing file nr SR-CboeBZX-2018-040, I strongly support the listing and trading shares of SolidX Bitcoin Shares, which has been issued by the VanEck SolidX Bitcoin Trust.
This fund seeks to target high net-worth investors, so I do not see a risk to retail investors. To the contrary, I think and ETF that is backed by actual bitcoins versus futures, is much more healthy for the market and will provide more stability!
Thank you and kind regards,
