It's a repeat of May/June. Big dumps coming soon.
It is normal to always prepare for a big dump after some huge pumps like this. I will not say it is healthy for now for most of the alts anyway as this just seems more of a market that is being driven up and I have the feelings some people are doing this to get some profit from the market. Altcoin support is still a bit not too solid compared to bitcoin, so it is best to get ready.
It is just the way we have seen it and in as much as we are seeing the bulls taking over does not mean a time will come when the bears will be having a filled day as well. It is a good thing though seeing most of these markets testing the tops and then the rapid growth within a short while. It is normal to be worried and I am worried too, but as long as we stay safe, we should be fine.
