What do you mean exactly when you say a fake coin? do you mean scam coins? then yes, there are a host of them. this coins mean no good, and they were in the first place created fpr selfish reasons. only a few were birthed from a place of good intentions, and didn't just succeed cos of certain limitations or some unforseen circumstances.
If there would be only "a" fake coin that would be perfect but every day there are being created new altcoins which are known as shit coin or fake coin until they prove us the opposite.
Many coins that were successful in the past have been shut down and are delisted from the exchanges because nobody is going to buy it or cost near to 1 satoshi mostly.
