Bitcoin is the slow and steady that's going to win the crypto race. One day very soon a hardfork is going to come along that's going to make BTC do everything all the other cryptos do and more.
The other cryptos have their purposes now, such as Ether in regards to smart contracts, but none of them have nearly the network or public awareness of BTC.
Truth be told, BTC doesn't need to be updated quite yet, as public awareness still hasn't caught up with it as it is. Even if BTC did microtransactions, the public at large wouldn't adopt it yet simply because they don't have the proper motivation to learn something new. Mark my words, though, when the public is ready, BTC will be ready for them, too.
