Topic: Super confused; in 10 minutes I went from $440 to $408. - page 2. (Read 1349 times)

How is this possible?

During this specific time, there was only fluctuations of ~$4-5. I deposited 1.7402113 from my exchange account into my BlockChain account. When I sent it from the exchange account, it was valued around $440. In the 30 seconds it took to arrive in the BlockChain account, there was literally no change in value.

But in the BlockChain account, on the top right, it shows up as $423. I started investigating right away to figure out where did so much vanish, and when I came back to the account about 2-3 mins later, BlockChain says I have $413 or something. So I quickly sent that to someone who I was supposed to send that BTC to anyway and by that time, it became $408.

My first question is how did it go from $440 on one account to $423 in BlockChain and second question is why was the value hitting low so fast? I looked in API and transaction logs, and I didn't see anything suspicious.

The other problem is this is a new exchange I used, first time, called CoinTrader. Granted they had bugs in their own system but I don't think values would get affected that much. I've never had that issue when I used another exchange called Vault of Satoshi. But since they're closing, I had to start using CoinTrader.

Here's the graph for the start and end times.
Please help!!
