I didn't understand your question but I am thinking that you want to ask in which coin you get a big loss. and my answer is ENJ I bought ENJ in 4$ per ENJ now it is the price is 2$ per token 
As for the example of loss, I think there are lots of coins that you can mention here, but if you refer to the OP's question then there are only a few coins that are suitable to have as long as you have enough patience to hold them until you are profitable with them. We all understand that we all have the same problem with some altcoins that we bought. If we bought at the top, we have options. To sell with a few loss or hold until it goes back.
