With all due respect, i disagree with your argument, i think bitcoin will still continue to dominate the crypto market for a long time, altcoin will gradually appreciate in value but bitcoin will not lose its value or position to the extent that people will have hard time spotting it.
I personally feel that in time to come there will be stiff competition between bitcoin and altcoin and i still see bitcoin dominating them all but not with the current margin...
Thanks for your view @mejustandrew
