shitcoins like ethereum can't solve their own limited functionality and the backdoors they have let alone attempt at bigger more serious stuff that bitcoin is dealing with 
Let me laugh at what you said. Bitcoin is just lucky to be the first on the line thats what it makes its price dominating and aside from that a lot of people are still confused using it. Ethereum transactions can be confirmed for only 20 seconds while BTC takes 10 minutes, so which is the best for you? lol
