I need trading advice. 

All alts are down big.  I currently have an alt that is down about 80%.  I have a bad vibe about it now.  The fundamentals have changed for the worse.  They have missed the road map 2 times now and I just get a bad feeling overall. 

There is another atl coin I really like.  This coin is also down around 80%.

Is it ok to take the loss if I move to a different coin which is also down a similar percent?
