I made some math with bitcoin here my thoughts:
MAX circulation supply: 21,000,000 pcs (the max bitcoin can be create)
Circulation supply / market cap = price.
Price * Circulation supply = market cap .
1,000,000 * 21,000,000 = 210,000,000,000,000 $ market cap haha
so if bitcoin will reach 1M all the money in the world will be in there.
bitcoin born in 2009 wich mean 50 years not that huge age to die before thats my opinion sorry about my language
