Are you implying these new fads like Lisk and Waves have a bigger potential to impact the world than Bitcoin? There is a reason why countless big name companies are investing time and money into researching Bitcoin, and not these flavor-of-the-month shitcoins.
There are many roads that lead to Rome. A market with many competing cryptocurrencies is far more healthy than a Bitcoin monopoly.
What's important is that all these different approaches - from Bitcoin to Ethereum, Iota, Lisk etc. - contribute to improve cryptocurrencies in general, one can learn from another. "Fanboyship" for one single currency is mostly based on greed. Bitcoin is the leader, for now, but that can change, or not, who cares. And yes, Bitcoin has a scalability problem. Not only because of the blockchain size.
