Um... a ~£200 transaction fee?? That's... not normal
1PfmdNxnZM33DxQGvmRmp7955Hf3yYz3cK is me, 1NmPv8sFKkhMJsNYeb5cGkzVpY86B9g58u one of my change addresses, and 1G3XsAAsHcfreztMixxLUe4V8WKNPt5V3c is my deposit address on an exchange.
I just bought .7 BTC tonight, sent .3 to an exchange, and when all the confirmations had gone through my balance was 0.1 BTC.
This is all I can tell you
I am phenomenally confused right now, and pretty stressed at what I am seeing.
What the hell do I do, if anything??!
