After all the hundreds of topics about BTC ETFs you still do not understand the difference between futures ETF and what has been talked about in the last few weeks, which is the spot (physical) BTC ETF that until now the SEC has consistently rejected.
How did you know if I read the topics and the replies? Or is it bad to ask a question of what that I do not understand? This sounds harsh and I think you should be polite in your discussion.
If such an ETF were approved in the US, then that fund would have to buy BTC to sell shares in that fund to clients. It is obvious that if someone buys BTC in large quantities the price will go up.
If I understand your correctly, spot ETF bitcoin means an organization will buy bitcoin on your behalf, which can be through the stock market, making more people to be able to buy bitcoin but indirectly. The more people buy spot ETF bitcoin, the more the price of bitcoin will increase. That is great, it is very different from future ETF. It is just like the GBTC from Grayscale, but better because more people prefer spot ETF in stock market.
I can also claim that everyone who bought BTC through CEX and keeps it there actually bought nothing but an empty promise that the number representing the amount of BTC they bought is correct, although the numbers on the screen are one thing, and the actual state of the funds is something completely different.
Why should someone use CEX to store bitcoin. That is not good and the people doing that are putting their money at risk like what happened to FTX users and users of many other hacked exchanges. Bitcoin ETF will be better, it will help in bitcoin adoption. But I can not go beyond having my coins on noncustodial wallets, having the real bitcoin directly.
