Amazing turn of events where now bitcoin is rising and bitcoin cash falling. Bitcoin is close to all time high while Bitcoin Cash is still double from where it was a week ago but falling, and around the $1k mark.
Even though they are related and intertwined they both have separate road maps. Bitcoin really is the core asset of crypto. All exchanges accept bitcoin and trading pairs with BTC is the most. Basically bitcoin is the standard of crypto. On the other side is BCH which is trying to make crypto transactions faster and security more robust. Basically bitcoin cash is trying to become the most common coin used in transactions.
Why then would bitcoin with all its flaws still be priced so high? It is likely because it has built itself as a standard commodity. So many miners are putting their hash rates into BTC that the global network is too strong to break off significantly to other coins such as BCH. The way bitcoin has establish itself as the most valuable crypto is not by its technical specs but because there is just so much demand/support for it. Inherently this makes bitcoin much more valuable than all other cryptos. BCH stands to want to replace BTC but if it is basically designed to transfer much easier than BTC then what is not to say people would rather hoard BTC than BCH?
