The best challenge for Bitcoin is to stay at the top as the most high valued cryptocurrency in the world but it takes constant support from investors especially today, there are panic selling and buying at the same time. Selling Bitcoin and buying Bitcoin Cash, miners are moving into Bitcoin Cash and a lot of changes that leads more people into confusions. Some will hold their Bitcoin hoping that the following day Bitcoin will rise again and surpass the recent highest record.
But none of us see it coming. Maybe next year is the year of bitcoin cash and the following year is the year of another.
I think if that happens I honestly think we're done, the whole market will crash and cryptocurrencies will be remembered like tulipmania.
Bitcoin ties it all together, if it was to be replaced by Bitcoin Cash, what's to stop someone doing the same to Bitcoin Cash later on?
Bitcoin is seen as both an investment and a store of value, who's going to invest or store value in something that can be replaced every six months, leaving your investment worthless? That's what these coup attempters don't get, they can kill the whole thing and make crypto a joke.
If Bitcoin Cash replaces BTC I think I'm cashing in my chips.
