Hi there!
This thread shall be about the mental aspect of coping with Loss.
The mistake you made - and still appear to be making - is that you measured your gain/loss in dollars.
If it's only more dollars you want just work more hours.
If it's bitcoin you want then buy, hold and stop measuring your success in dollars.
Do one or the other but make up your mind.
I bought bitcoin in 2013 because I thought it was an exciting phenomenon and I wanted to have a "horse in the race". I wanted to be in bitcoin - not in dollars because I thought it was an immensely powerful technology and had a bright future. I measure the success of my "judgement" in terms of adoption, proliferation of understanding, consolidation of the technology etc, so I don't feel depressed, I feel great. 2014 has been a massive year for all that. All that happened with the price is that it consolidated from a big rise which is what markets always do after a big rise.
Either stop feeling sorry for yourself and be happy that you've got any bitcoin at all, or sell it all if you're no longer interested in the technology and don't touch it again.
The only people who successfully use markets as a guide to what they value are professional day traders.
