FYI - Ethers are as different from bitcoins as oil is from gold. Ethereum platform is as different from the bitcoin platform as banking is from law. OP is stupid.
But. If bitcoin doesn't get it's political & scaling shit together it will eventually be overtaken.
"Bitcoin is supreme because it's been around for six years. Your shitcoin will never replace it - bitcoin is better."
"Why is it better?"
"Because it will always be the leader since it's always been the leader."
Bitcoin maximalists as a general rule give arguements that're as sound as the OP.
