Bcash is just an altcoin how can you compare it with Bitcoin. Dogecoin and Eherium it's competitors at best

I wish that were true. BCH is basically BTC, but without as much community support. I hope that does not change, but who knows. I want BTC to win, but time will tell.
Well it is a past part of bitcoin, so you can say that it is an ex-part of bitcoin. It can't be say that it is a Bitcoin because Bitcoin Cash part it's way with bitcoin.
You don't support Bitcoin Cash still you're comparing it to bitcoin.
