To whom it may concern,

I think now it is good time to for SEC to aprrove ETF as Bitcoin has been mature both on mass adoption and technology wise.

Bitcoin now is a well-known commodity all over the world but the market cap is too small now as institutional investors cannot access the market officially. As such, Bitcoin market now is easy to be manipulated by cartels or whale alliance which make Bitcoin price is so volatile.

SEC approval can help to bring trillion of dollars from institutions into the market, making it a strong, more stable and safer for investors of all kinds.

Technology wise, Bitcoin infrastructure is very solid now, fully decentralization makes bitcoin almost unbreakable to any attack. So security is not an issue now. By the way, developing Layer 2 technologies will empower Bitcoin to be widespread to thousands of people.

To brief, the high demand of ETF approval is undeniable and here I hope that SEC will play its main role to stabalize cryptocurrency market as a part of global financial market as it should be.

Best ragards,
