I have come across so many different digital currencies that are no longer profitable for miners who are hunting opportunities. What would we think of coins that show up in the scene and never reach a real valuable exchange rate against Bitcoin or USD? It is known that those coins as any traded goods are subject to the law of offer/demand and the volume of the trades (market capital), the more the users and adopters of the coin the more it has value (increase in its value against USD or BTC).
