I believe the more support the CC community gives to all currencies both scrypt and SHA-256e the longer they will exist and the more valuable they will become. Especially if we completely mine out an already existing currency. Plus the more exchanges that support them the better they will preform. The more money and CC we invest in the system the less of a chance they will fail and the more they will be accepted on a global scale. Who knows maybe you'll be able to buy gas a the station will an Credit card, cash and Zeta coin combination
