It's better to talk about real value of Zclassic after spending time to analyze about it's intrinsic values. After that, you can have good evidence, good reasons to make a conclusion on whether it is a overvalued or undervalued coin at the moment. All judgements should have bacground, not mainly based on emotional ones.
Looking at the Zclassic chart, it's not strange to see the coin rose last days. I don't want to call it as undervalued coin.
