I don't think so - it would take a whole lot more than a hundo to 'easily manipulate' the market. Why do you think whales are called whales instead of guppies? They don't even notice making or losing a c-note. How do I know? Am I a WHALE?!! Nope, but I personally know one who was playing with BBQcoins. He could swing the market, but it took about 40 BTC to do so.
You can easily manipulate MINT with less than 100k. Each market is different, but 100k can make MINT go in any direction you want. 100k USD is roughly 810,000,000 MINT. One can definitely manipulate the Mint market with 810,000,000 MINT.
