But for institutional investors, it's massively different because they invest clients' money and there are rules. In this case, they are obliged to choose wisely and protect the money.
I referred to both individual and institutional investors in that post. The shrewd ones among them wouldn't want to invest when price is going up to chase it, except they don't pay attention to TA. I saw what El Salvador did when she bought for reserve. It wasn't at a moment of dip that period. In fact, the market dipped after that. I've read a couple of Bitcoin purchases made by Blackrock and we can't say they were made at a moment of dump.
However, you do have a point where you mentioned there are rules that govern institutions and their obligations to their clients. Let's assume that one of such rules would be for institutions not to hold down clients' funds beyond a certain duration without investing such. In that light we might find a reason to adjudicate that price level won't be their consideration but beating deadline.
