Ethereum Classic, as everyone knows, is the original Ether Coin, and has more time in existence than many other coins, including Ether. With increased popularity and support, this coin may be on the rise to $5 or higher if it steps into the trends that ETH, DASH, and many other coins got onto, and as these other coins begin a selloff, ETC may be the coin to get some of the buy-in.

In fact, many investors have ETC valued at $20 per coin.
