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. Once can definitely manipulate the Mint market with 810,000,000 MINT.
Oh, I'm sorry, I was assuming that your decimal was a, uh, decimal since you were making it in reference to USD. My bad, I'm clearly at fault here. Just because I learned that commas (,) are used as 100 place separators in school here in the U.S. doesn't mean it's right. Stupid public school systems! I bow to you my liege. Please tell me what else you predict - I'm literally holding my breath.
