If in 10 years time, bitcoin is $10m each, then the cash reserves of MSTR stored as bitcoin would probably form a majority of their market cap. At that price and if they don't get any more bitcoin, that puts the company hodling 1 trillion dollars worth of bitcoin.
There are several other companies that exceed this marketcap today. If those companies attempt to buy bitcoin, they can easily surpass MSTR.
Apple is 2 trillion. Microsoft is also 2 trillion. Google is 1.8 trillion. Amazon is 1.6 trillion. Facebook is 1 trillion. MSTR is about 6.8 billion, with almost two thousand other publicly traded companies larger than it by market cap. They were half that last year; I mean MSTR was 3 billion last year, this year they are 6.8 billion.
Facebook is going to launch it's own shitcoin, but it can, and probably will, also hold bitcoin in its balance sheet.
The question is, will MSTR maintain the lead and be number one with 100k bitcoins? Will other companies try to follow? There can be only 200 other companies that can possibly do this and stack 100k each.
This might be the most bullish thinking for me, if 2000 companies only buy 10k each, that would be the same result, more or less.
The total market cap of the top 5000 companies approaches 93 trillion dollars. They're not all going to buy bitcoin. But if half of that goes to bitcoin, we're looking at 2 million per whole coin. Markets don't work this way or linearly, so the actual effect could be much higher, which is why it's not too crazy today to think bitcoin can go up to 10 million to 50 million or even 100 million per coin.
We know the big banks (edit: I typed big bangs) are eventually going to buy some bitcoins, ... because they will be accepting them or offering custody services for them.
Probably a good description of them in the coming months/years...
