Greetings SEC,

It is with esteemed pleasure that South Side Blockchain supports approval of a Bitcoin ETF. A Bitcoin ETF can validate and help the digital asset class mature. This ETF would be advantageous for traditional investors who may not be knowledgeable in operating blockchain technology, but want to get involved. With this approval, institutional investors will become stakeholders in the growing blockchain industry.

Most notably, a Bitcoin ETF will advance the United States of America's position as a global leader in cryptocurrency adoption. Doing so establishes an economic system where everyone: working, middle, and high class citizens have equal opportunities to invest in cryptocurrencies/blockchain protocols.

We hope the SEC recognizes the benefits of approving a Bitcoin ETF. The advantages will be foreseen by traditional investors, institutional investors, working, middle, and high class citizens. In all, this approval would progress the American economy.

Sincerely,

South Side Blockchain
