Every project is focusing on an issue and tends to say that they're the answer to it. But bitcoin has solved what most of these projects are aiming for and that's both, a payment method and an asset. There will be arguments that'd say that if there's another project that has come earlier than bitcoin then it won't be bitcoin on its seat now. But to be honest, there have been the same project concepts that have been introduced before but they've failed or just got little attention unlike what bitcoin has reached. Honestly, bitcoin is more than enough already, there could be scaling issues and network adjustments needed to be made but looking at it, it's much better than before.
