If 5000 each, market cap would be around 100 billion
Current market cap is around 8.5 billion
How grow up bitcoin price to 5k: put 91.5 billions of fresh money there. Seems harder than walk to millions to billions
Patently false.
The market cap is simply the price of a single coin multiplied by all the coins in existence. However if you tried to buy or sell that number of coins the price would massively fluctuate.
It only takes a relatively small amount of direct currency investment to drive the price up (or selling to drive it down) in comparison with the market cap because the market is so thin.
This is what will drove previous bubbles and what will drive the next. Hopefully with an ETF providing even more of a liquidity suck.
