I take it Peter is now referring to Bcash as the one true Bitcoin. True to form.
No. You take BTC as "the one true bitcoin." As for me, I say that I
don't know. Maybe BTC will remain dominant; but maybe BCH with its greater block size limit will overtake it. Or maybe a new branch will prevail. It doesn't matter to me because Bitcoin is the sum of its forks and I hold them all.
Unfortunately, it appears that in all of my views of this web page,
https://txhighway.com/, the one lane highway is still being used much more heavily than the 8 lane highway.

It appears the BCH proponents have a long way to go to get anywhere near the adoption BTC enjoys now. This is despite the BTC mempool being at times so clogged that it is "unusable" as BCH supporters have spouted out time and time again. Or the recent narrative seems to be that BTC now has low fees because it is losing adoption. Well, that may be true, that BTC is losing adoption. However, as the web page that I have linked to demonstrates, time and time again, BCH is not gaining adoption by leaps and bounds.
