Why is the usage of forking?
Trying to manipulate the market due to self greed, in an attempt to squeeze out more Bitcoin from others.
This response couldn't be further from the truth. The reason for a hard fork is an attempt to propose an improvement to the Bitcoin (and its blockchain). A success would lead to a better "bitcoin" and a failure proves that the a majority of bitcoin miners believe that is good as it is.
How could it be a better bitcoin if it will be named as a different coin, so what will happen to those people who invested on bitcoin on the first place if the fork became successful that lead to a "better" bitcoin? So if a fork was successful that only means that "bitcoin" will be an alt coin right?
does forking give any advantage to the users?
No. All it does is create confusion and possibly damage if there is no replay protection. Roger Ver, Jihad Wu and co. are mostly responsible for those.
No. It could offer a benifit, that's why a fork is proposed. Roger Ver hasn't had influence in all forks, so stopping talking shit!
What benefit can a fork offer? What I understand is that a fork is like an ICO without offering it but it came from the records of
BTC and a new is created, so which one should be considered as an alt coin?
