I'm not sure if altcoin can beat bitcoin, except the altcoin can work with government lol, regulation and bad news from the government on bitcoin can lower the bitcoin price, but from what I see if the bitcoin price drops it will also affect all altcoins for example today.
The relationship between the BTC and the alts is a quite complex one. When the BTC values are up, the alt prices rise even faster and as a result the Bitcoin market dominance drops. On the other hand when BTC crashes, the alt prices crashes even more and as a result the BTC market dominance increases.
