All eyes are really on the Blackrock Spot Bitcoin ETF purely because Blackrock are the
largest asset management company in the world!
And most people expect the SEC to agree and on the other hand also compare the performance of the financial industry in the past and the results BTC shows that this will be the safest and smartest investment in the future and the way is to buy bitcoin itself. Bitcoin is basically a form of currency like USD and EUR, only it doesn't have a physical form and is instead stored online on a computer. BTW, we'll see in January 2024 whether it will be accepted or there will be another delay by the SEC like before.
There are many differences between bitcoin and EUR and USD. Besides the tangible and intangible differences, bitcoin is a decentralized currency, with a limited supply...it is completely different from the fiat money that governments are creating. Furthermore, bitcoin is considered an asset rather than a currency so I think it is more appropriate to compare it with gold or other financial markets than with USD and EUR.
Basically, there are already many bitcoin ETFs in other countries but people are still waiting for an ETF from the SEC because the US is the largest financial market as well as the world financial center. I believe the SEC will have to approve ETFs but they need a better time to make that declaration and the best time could be the Bitcoin halving event.
