Forks are bad. They are foolhardy
attempts to attack Bitcoin. But Bitcoin is stronger than all attackers, thus leading to an observed rule in practice:
You fork, you die.Genuine Bitcoin has crushed numerous forks and attempted forks: “Bitcoin XT”, “Bitcoin Unlimited”, “Bitcoin Classic”, and the “New York Agreement”
(misnamed “Segwit2X”; nothing to do with Segwit), to name but a few. These no longer exist. For the current outbreak of forks, if you wish to claim some fork coins, then dump them in exchange for real Bitcoin, and enjoy your free bitcoins. Otherwise, simply ignore. Anything from “Bitcoin Cash” to “Bitcoin Super Diamond Plus2X Plutonium With Ponies” is only a scam; and these scams will die sooner or later, just as did their antecedents.
There are many pretenders to the Bitcoin title. However:
There is only one Bitcoin.
