#Decentralization and the immaculate conception.
#Bitcoin is the only coin that is actually decentralized. There's no leader, no foundation, and no single group of devs that work on the protocol. It's the only coin that can withstand a government attack.
Fair distribution is important. Bitcoin launched with no value, allowing the coins to be issued and circulate fairly. All other coins had value at launch or were premined. This leads to advantages for first movers who were already in position to profit. No other coin can launch fairly now since value is assigned before launch.
Bitcoin is King.
