Certainly there is always a chance for ethereum to be pumped up in value. But it is for certain that when something is pumped up the next thing that could happen is that many will eventually be dumping their coins which is also a bad idea. Because it will somehow create a landslide followed by FUD and again many will be losing their investments.
You need to know that after the pump is the dump so don't just look into some pumps and say that is potiental or that's huge profits, nothing in this world is save my friend even with the normal investment.
If you aren't serious, you could lose in it also.
