Hello,
I also noticed massively pricedroppings, thanks to China.
Fortunately, i only had 1 BTC and 1 Litecoin for which i diidn't pay. However, on a Dutch forum some people where panicking over the massive drops.
Lots of the members either went Short or just hang on to their BTC for live.

I think there's no need to worry. Price's might go back up again, as it looks like it's doing now.
I just wish that i went into the mining when i first read about BTC, which was back in 2010 or 2011.
