We have coins with some awesome project, so why is btc regarded as the king of coins and it's so unique than others?
It's not only about the technology that it can offer but also trust. Bitcoin is the king not just because it is the first cryptocurrency in the market. It is the king because of trust of the community. Since it is created years ago, the supply of Bitcoin is more scattered in many users. That is why it is harder to manipulate compared to altcoins.
