So, BTC price is a question of supply and demand - with a pinch of salt regarding the large amounts stored with little movement. Bitcoin has been building it´s credibility, first with small highly convinced people, then some mouth to mouth, then with help of some internet blogs, this forum, etc... and now is getting the attention of the huge investment funds and capital managers.
What next? What would drive the demand once the big players build their stakes?
By the time big players have built their stakes, there will be a much higher fiat price and eventually more stability. Another order of magnitude or two (or more) is easily possible. An ETF in addition to mutual fund investments will drive a lot. I presume that is what you were meaning with regard to "investment funds and capital managers." Given the very small interest from US corporations so far, once more get involved (Mass Mutual, Tesla, MSTR being very early) demand will continue to soar. And then there are corporations in the EU, Asia, South/Central America, Africa etc. Corporate adoption like the ones I mentioned above is extremely low, perhaps akin to 2010 or so. MSTR is Hal. Tesla is Laszlo. Perhaps the MSTR presentation in early Feb 2021 (

Inflation protection for everyone may become important given the huge amount of stimulus over the last 10-12 years, let along just the last 12 months.
