I will never understand why any bitcoiner would be fearful of ethereum or vice-versa. Is just 2 different blockchains with way many differences that makes them both valuable.
I'll explain it so you understand. The most significant promise of Bitcoin as a value store is that it's supply is limited - 21M bitcoins. Proliferation of alts breaks that promise. Now there are 21M bitocins, plus 90M ethereums, plus miriads of other cryptos.
