Alt= alternative = price still tied directly to bitcoin.

Little bit of a problem there.

Can't say if your decision today was a good one or bad one, because nobody has a crystal ball.  But the trend certainly looks gloomy. 

This is also a classic case of why you should only invest what you can afford to lose.  I lost a bit too when I sold majority of my holdings at 3xx after paying around 5xx for them, but looking back...I'm glad I did.  My gut told me things didn't feel right, and I sure as hell am not going to keep 'loading up the truck' on a falling sword in attempt to lower my loss average.  Learned my lesson from silver.

Wish you the best whatever path you take.
