BTC is controlled by whales and the richest families such as Rockefeller, Rothschild, Soros... They own the companies and institutions related to BTC. ETF will be posponed on September 30th, then price will have a massive fall. Those organizations will take advantage and buy all BTC they can in numerous wallets. On February, ETFs will get approved and BTC price will rise a lot even to 100,000. Since people will invest on BTC, trillions and trillions of dollars will enter to cryptos. However, BTC will be even more controlled by the richest families (the real whales) since they have bought a vast majority of BTC when it was low, owning the 60-80% of it in private wallets and making people invest through ETFs.
I think its likely that ETF will definitely affect the price of BTC and that will make lots of people to buy in especially if at a price rise. And yes, this may include the rich but also new investors, at least we should be happy that there's faith in the BTC future
