I totally agree with your point that it is not practical to use bitcoin for everyday needs and that there are too many crypto currencys out there. But we are just at the beginning of crypto currency development. In some years, there may be a lot less shitcoins around and the global acceptance may rise even more, if we give it some time. On the other hand, governments may ruin everything by putting too many nonsense regulations on crypto currencys or even outlaw them, like china or South Korea.
