Well, it's most likely going back up once RC4 is out and everything is working smoothly. It may not make you rich over night, but I don't see you getting out at a loss. It's just gonna take a while.
However in Crypto shit can turn south any second, regardless of the coin. So if you really rely on that money and can't stand the uncertainty, you might wanna grab what's left of it and get it over with.
#edit: is there any interest in having someone run the remote part of a masternode for you for something like 2DRK/month? No Linux hassle, just paste provided data in your darkcoin.conf and go for it. You'd remain full control over your funds at any time.
