Hello

As an environmental scientist, I believe that this ETF can address many of the environmental issues that many people pointed out. The very important thing the public should know is that Bitcoin miners don't use special electricity dedicated to Bitcoin miners. Do people really believe that Bitcoin mining rigs have diesel generators attached to them or those mining farm owners have their own coal-fired power plants? The answer is NO. Most of them just use the common electricity that directly comes from the power plants. They just consume lots of it. If they want to blame bitcoin for using so called dirty energy, they should blame the electricity in general.

When people blame Bitcoin for not using renewable energy, it just means that renewable energy makes up only a small portion of our overall energy mix IN GENERAL.

That is why we need to see the approval of a Bitcoin ETF this year since renewable energy is the fastest growing energy source in the United States. If a Bitcoin ETF is approved, American entrepreneurs will have more confidence in Bitcoin because they can clearly see that Bitcoin is now being regulated by our regulators and they will start mining Bitcoins here in the US instead of in other countries where clean energy sources hardly exist. Also, think about this administrations $2.25 trillion infrastructure plan to focus on green energy and decarbonization. It is the perfect time to bring the Bitcoin mining power to the US. It will create many jobs here in the US and help our economy grow.
