I'll repost it here.
Here's my experience with mintpal and cryptsy.
This one happened twice already. The buy order I was supposed to dump at disappears when my deposit is about to arrive at mintpal.
I did a test one time, I just monitored the buy order at mintpal when I had a chance to arbitrage with mintpal and other exchange and there was a high bid at mintpal. The buy order remain there for hours... but of course, if I try to buy at other exchange and deposit it at mintpal, that buy order will disappear before I could dump on it. LOL!
Sigh! Mintpal did it again! Bought some GUE at bittrex at 2.8k because I saw a 6500 buy @3.1k at mintpal. So I immediately sent it to mintpal then I was wondering why it's stuck at 8 out of 10 confirmations. I keep refreshing the page but it's still 8 confirmations while it already has 17 conf.
Then suddenly, someone else dumped at the buy order I was targetting
Then after the buy order is gone, that's when my deposit was credited at mintpal! I'm starting to hate this exchange now
Here's another one. This happened twice already.My buy order doesn't get hit because someone will suddenly appear and block the dump by 1 satoshi.
This one happens when I'm logged out of the exchange. That's why I always remain logged in now and monitor the orderbook
Mintpal! What a crook! I placed an order yesterday at 0.00015020 and the price only dropped 1 point higher than my order. The next orders are at 0.00015300~ before I logout and just monitor it at bitcoinwisdom. Few minutes later, I noticed it got dumped and someone magically appeared at 0.00015021. The buy orders was thin because it was dumped recently up to 0.00015018..
I wonder how someone could possibly place a buy order faster than the guy selling BTC and catch his dump.
Or maybe it was mintpal selling BTC to his own buy orders to pump volume while avoiding the REAL buy orders?

And here's with cryptsy, they suddenly slap me with a negative balance when I emptied my balance on their exchange. They're blaming it on a trade I did long time ago. And they also held my withdrawal as hostage. LOL!
How long does it take to confirm darkcoin transactions? I tested withdrawing from cryptsy to mintpal and it's been 45mins and it's still no confirmations. Cryptsy also gave me a negative LTC balance? LOL!

I've confirmed the withdrawal from my email an hour later and waited 6hrs but still, the withdrawal wasn't processed. It appears that they kept it as hostage because they say I owe them -0.00017388LTC. That's just $0.00172. LOL! I miss my arbitrage opportunity because of that!
