But bitcoin is not VHS and BCH is not DVD. Speaking your terms, if bitcoin is VHS, than DVD is ethereum, eos or projects like that.
If bitcoin would ever be replaced (at least surpassed in capitalisation), that'll be an altcoin which is technologically more advanced by design. But not a fork.
Ethereum is no where near btc but bch /bcc have really created a good pump now it is trying to attack through transaction problem by not giving hash to confirm the transaction so that btc could die
ethereum is essentially controlled by two guys, one of them a little man-child geek, who thinks he can adjust the source as he wishes to decide who wins & loses in his 'ethereum' world, nobody is going to fall for that game.
BTC is consensus, as dreamed by Satoshi, likened to herding millions of kittens in space.
BCH NYA are all attempts by GOV/BIG BIZ to control BTC
For now the little people, the kittens remain in control
Note if the assholes can't take over by political means, then they will use GOV, and control BTC by brute force, well at least they will try,
For now, BTC is to important to be controlled by the 'kittens' so thinks BIG-GOV-INC
Satoshi was an anarchist, he hated GOV, and wanted the kittens to have their own banks, and their own money.
Today's money is DEBT, which is slavery
BTC is freedom where every man-cat knows what he owns, and is in debt to no asshole or GOV.
