Even though I only invested in Bitcoin what I really can afford to loose, the loss would still be felt, and that was affecting my decisions.
IMO this means you were still over invested, even if you could afford to lose it.
My next move will be to free myself from this fear. It has a price, and it's Bitcoin denominated. I am going to sell and withdraw some fiat, covering all my investment in Bitcoin purchases, purchases of the mining equipment, plus a small revenue on top of that. What's left, will be completely emotionally detached from the rest of my economy.
This is exactly what I did at $960 before this crash. That money is still on the exchange, but I'm not buying in with it again.. just waiting for today (Monday) to withdraw. I have to say it feels really good to have sold off my initial fiat investment and to be free-rolling now. No matter where it goes now, up or down, I've still made money, and I'm still on the Bitcoin train. I'm not over invested, and I'm not under invested. And best of all: I don't need to watch the prices. I can just sit on this long term.
Oh, and in the amount that I sold off I also included money for investing in other things. So I'm diversifying my portfolio.
