All the fork of bitcoin mentioned are made last year without any recourse to community demand of them. Do we need any of this bitcoin fork? The answer is no. Altcoin is not bitcoin and they are valuable for some other uses!
All these forks were just made to divert the attention of the investors from bitcoin, I think. They have not resolved any problems at all. All these forks promised to give us technology far greater than BTC but turned out to be just another altcoins.
