My understanding is that the transfer fees for Bitcoin will not be returnable - these will have not gone to your supplier, but to the miners processing that payment.
Makes sense. I guess I'll be better off just sticking to the compromises I had to make and not cancel or modify anything just to make sure I'm not losing 150 USD on nothing. After all, it's a damn free 8700k+motherboard, GTX 1070 Ti and RAM, things that I would have had to save for another year and with this they basically fell off the sky just because a few nights of mining in 2011.
Oh well. Thanks for the reply!
