It's not going to be that easy. BTC is the most widely spread coin. Stability is achieved by having a vast number of people use a coin. BTC has got such a massive fan base because it was the first, people didn't have any choice. Nowadays you've got dozen of new coins coming out every day. And every new coin has to have amazing features to be able to attract believers and even then, it's only until a 'trendier' coin comes along. There is too much competition for a single altcoin to win the world like Bitcoin did. It could happen but chances are slim.
