Care to explain what is actually here? It seems to me that there is some sort of a silent panic happening all over the Bitcoin holders worldwide. Some are listening to the FUD that Bitcoin is about to die and be replaced by Bitcoin Cash soon...how true can that be? This is one of the most uncomfortable times to be in cryptocurrency where people in the same industry are killing each other...oh I forgot it is all about greed and opportunism...we are still dogs anyway!
I'm not an expert- but here's what I know (quick explanation) - if I say something not perfectly correct please do not get on my ass - I'm just trying to help :
The blockchain will get validated by the nodes (miners).
As soon as you have a majority of nodes ( 51%) confirm (approved) it would become the longest chain - then it become legitimate.
Right now the majority of the miners are for Segwit 2x so they will confirm any bogus blockchain that coming their way...thus tons of blockchain could potentially be illegitimate (fake).
