Definitely - Bitcoin is the KING - the first and the greatest. Bitcoin cash quickly grew in its best of times. Then there were reviews in the media reported that bitcoin cash is a real replacement for bitcoin. However, everything fell into place. Bitcoin first.
There are no reviews about Bitcoin Cash being a replacement for Bitcoin, except those being generated from Ver and Wu.
You are right, Bitcoin is king. No coin, token, innovation or crypto has taken over from it.
