I recently got acquainted with an article in which it says that bitcoin is killing Bitcoin Cash, despite the fact that Bitcoin Cash has an emergency complexity change mode, in which the complexity of the blocks falls by 20% in the event that in 12 hours there are less than 6 blocks . Nevertheless, Bitcoin Cash has more significant drawbacks than the classic bitcoin: it is the instability of the network, the too rapid emergence of new coins generating inflation, 4 times the inflation bitcoin (16%). further - reduction of compensation for the miner for every 210,000 units. and the last: the Bitcoin Cash network is more vulnerable to attacks. from this we can conclude that the classic bitcoin is more reliable and long-term than Bitcoin Cash.
