I don't think now with the high price of bitcoin BCH can't surpass BTC in payment functionality
I agree with this statement. In the near future, BCH can not overcome BTC in many ways. The market is now supporting the BTC for liquidity and the currency that is leading the current trend. Hopefully in the coming time the Executive Board will be put into many applications for payment. At that time, the comparability between EB and BCT would be more balanced.
