True, the biggest money is there - but also the biggest risk for Bitcoin. Unless someone thinks the WS will embrace BTC as something worth more than just a means of making a profit.
Max supply is still 21 million, unless some nonsense happens and someone manages to change it in the future - and halving only reduces the miners' reward every 4 years by 50% which will eventually result in 99% of all mined BTC around 2030. In addition, we are approaching a circulation supply of 19 million, which may seem like a lot - but another 2 million is also a significant amount of BTC, especially in terms of their value, which is likely to increase constantly.
I want to say that people understand that only big players will be able to buy larger quantities of BTC in the future, and that they will need a lot of small investors to buy only 1 BTC.
