In the past 6 months, there was a popular topic about Ethereum for $200. And now will be replenished with messages such topics as: ETH for $500 and so on. But they will be little useful and reasoned information( to my regret).
This often happens when everyone is competing in predicting or hoping for every coin that grows like ETH most often. It is natural and not prohibited because it will not affect the coin at all, but there is one impact that can cause disappointment and for the owner himself. In my opinion, this might reach $ 500 because of the rapid development of ETH.
