So you are worried about the current level of institutional adoption but on the other hand you are also happy with what bitcoin has achieved, ok man let's see if there were no them and ETF it might take some time to reach the current price and stability level, however the billionaires play a big role but don't worry bitcoin still cannot be controlled by any party its decentralized nature will remain strong and again anyone can own bitcoin there are no restrictions.
We can say that it's natural that others start taking notice and make their own moves regarding BTC - they only speed up what is already set into the gears regarding the adoption process.
