Greetings-

I'm writing this in support of the proposed ETF by the Cboe and the VanEck Solid x Bitcoin Trust for the following reasons:

1. Bitcoin and its blockchain technology is a revolutionary concept which is maturing rapidly both technologically and as a safe investment venue, and has proved its worth over the last near-decade of its existence by refusing to die, and continuing, with various setbacks, a continual upward arc in value.

2.Bitcoin itself has proved to be hack-proof. The exchanges BTC is traded on, however, have been hacked from time to time and have also proved at times to be fertile ground for manipulation.

3.The advantages of BTC being traded as an ETF on the Cboe are many: it provides much-needed regulatory oversight, it further brings into the mainstream a technology that will be mainstreamed inevitably anyway, and it will allow more cautious institutional investors to participate in a safe and secure manner the "next big thing" in tech.

The US has historically been on the cutting edge of tech innovation since the invention of the telephone. Bitcoin represents the next step in this innovative process. Other nations are adopting this technology rapidly, and we should not fall behind in this process.

thank-you
