It's already happened once with Credit Cards. Visa, Mastercard, and Discover all competed. And guess who won. Visa While Mastercard fights to catch up, and Amex, & Discover lost. If Bitcoin is the best it will beat Bitcoin Cash, Litecoin, Ethereum, XRP, Z-Cash, Monero, and More. If not then it becomes The Discover of Tomorrow, if it wins then it'll be The Visa of Tomorrow. The only way to truly tell what the best payment method is to let the top so good ones compete, & make the worst one face an uphill battle to get accepted. https://youtu.be/dA9ltGY_vv4
