I don't think Bitcoin Cash sudden bubble is a joke.
Bitcoin Cash is backed up by a scale of crypto miners who believes Bitcoin Cash can lead the way as the next Bitcoin.
The next Bitcoin is Bitcoin.
If it was going to be "replaced", there are hundreds of technologically superior candidates.
Bitcoin is loved and respected because it's everyone's dad, it's what started it all, it's not respected for upcoming tech or other attributes.
Bitcoin is Bitcoin, Bitcrash is nothing, just a shitty alt with nothing going for it.
Waves, Particl, Neo, Eth, etc. All far superior tech wise to BCH, if anyone's going to dethrone Bitcoin it won't be BCH.
