Damn I WISH i will ever get to 200-600 BTC. I am currently around 1.5 BTC when it's a good day. Started with 3000-4000$.
BUT i have to say that you have some great bags and i really believe that if you held it through this long you might aswell stick with it. When the bull hits us again some of your bags will definently take off.
Keep the spirit high and don't see it as a loss as long as you still believe in the projects. The projects/coins haven't changed since you joined, only the market, so trust your buys.
Good luck out there!
