market cap is a meaningless number
i can create an alt tomorrow with 5trill coins.. get just 1 coin on an exchange and sell it to myself for $1.. and instantly my alt is market capped at $5trillion...
Agree 100%, market cap is a meaningless number.
Its good that altcoins exist, its like beta tests for possible new features in bitcoin.
But some people still consider to buy alts from its marketplace so it's not obvious.
