This infographic sums up my thoughts on this.
See that tiny dot above the words: "bitcoin $19 billion"?
That's bitcoin's market cap in comparison to the global economy which is pictured to the right of that.
You really cannot compare the world economy to the crypto currency market capital ,there is a vast contrast and it is really not fair comparing the both markets.When it comes to the alt coin markets there are really a lot of shill coins and some of the coins are really over valued ,so i do not buy this one up,what ever manipulative the world economy is,it has a structure and a base and crypto market is not here to challenge all the conventional economic systems,but to provide an alternative solution in the digital era.
