It's already much harder to move the price of BTC: and it slowly will become harder and harder for institutions too, in my opinion.
A lot of bitcoin is concentrated in the hands of a few. Take Blackrock and all the ETFs or MicroStrategy, for example. They have what it takes to move the market. Bitcoin is a collateral for one type of bonds that MicroStrategy is selling to investors. If it becomes necessary to sell a big chunk of it due to a downward trend, it would cause a lot of panic selling, with other individuals and companies dumping their bitcoin.
I guess this became the disadvantage of Bitcoin now since those big institution could pull a manipulation antics if they want to create certain movements that aligned to what they want to happen. That's why this situation is I think goes in favor with those institution that hold a lot of Bitcoin since they can influence a lot of people on each action they made. That's why somehow people should stop basing their decision on statement release by those big players since that clearly state that they want to control people minds. Also we need to exert effort to get updated on somethings happening in the market so that we will not get left behind once those manipulators will do a big move that can possibly move the market.
But also when talking about Bitcoin could surpass Gold? I guess we will find this one in future, but we can say that everything has possibilities that it will happen.
