Purchased some Kylin token on Hoo exchange...it was a market order and the price was listed at $0.1530 USD...as soon as i clicked on buy the price jumped and it ended up costing me as high as $0.1674 USD even though Kylin never traded anywhere near that high on this trading day...so they overcharged me by 15%...I was so disgusted that I immediately decided to sell and the price then fell as low as $0.1474 USD from the $0.1674 it had been a minute earlier...I know that these exchanges have a slight variance from buy to sell price in order to make a profit but 15% is ridiculous...avoid these crooks unless you stick to limit orders where they shouldn't be able to gouge you(in theory)
