It's normal. Take advantage of the opportunities when you find them. Sometimes those deals that seem to good to be true, really are as good as they seem. There are quite a few bargains so do your homework.
It is really a huge opportunity to buy those coins very cheap now and wait for them to get pumped after the fork.
Not all of them though, cause some of those coins will take like months to recover from the sickness that befell them. For some potential coins though, it will be a very good bargain and lot of percentage increase in coming weeks.
