BCH proclaims they are the true Bitcoin and that they follow Satoshi's vision, so why is Bitcoin still so powerfull? Do you think in a not very much distant future things will change?
Community supporting BCH is relatively small while bitcoin still holds majority of support. Demand for bitcoin is really high and most of the Bitcoin supporters don't like to hold BCH because bitcoin is enough for now and with lightening network soon it will be almost free to send bitcoin through off chain transactions.
I don't think BCH will ever surpass bitcoin.
