btc can now buy anything on the internet using snapcard or gyft. the only other altcoin that comes close is litecoin.
still, litecoin is pretty limited but with more and more adoption everyday. now you can sell litecoins at litecoinslocal.org and get cash or other money transfers. litecoin is a good ways behind bitcoin but could catch up relatively fast and i think it will.
the rest of the altcoin you will need to transfer to btc or ltc to cash out unless you go through an exchange and do a wire trans to your bank.
so btc and to a lesser degree ltc have a strong adoption rate and advantage with more people working on related project to support their ecosystems.
cryptocurrencies are like start up internet companies and the ones with the best ideas and devs and support team will win, do your homework and invest wisely and you will too.
