Of course, many people care about it as the impact will be significant, but not everyone expects bitcoin ETF to be accepted though.
Significant but unlikely to be sustainable. We might see another bubble to form if SEC approves it.
Some say ETF could harm the bitcoin market and others contrarily, but one thing for sure is traditional financial institutions and more investors will acknowledge bitcoin and brings a huge influx of money to the market. Nevertheless, the chances of an ETF proposal get accepted are small due to SEC wants the proposals in some way deterring fraud and manipulation but the vast majority of bitcoin trading occurs outside of the US, which means there is no way to ensure protection against manipulation.
It could really harm the market in long term. as I have mentioned their might be a sudden influx, tons of money being push into the ecosystem, but I doubt that it going to be a sustained growth. We will give institutional investors or custodians powers that at the end manipulation will be very obvious that might sway away casual investors.
