We have coins with some awesome project, so why is btc regarded as the king of coins and it's so unique than others?
Because if it wasn't for bitcoin those coins will not exist to begin with, if it wasn't for bitcoin you will not have a currency that is accepted by everyone in this market and that allows you to trade different coins, if it wasn't for bitcoin you will not be able to pay for a number of products and services that do not accept any other coin, those are some of the reasons of why bitcoin is the best coin in the market.
