Bitcoin is valuable not because it has the trust of the people but it is because of blockchain technology.  Bitcoin arrived with blockchain technology which introduced decentralization ushering people in the financial ecosystem with financial freedom. I don't see any altcoin which is better than bitcoin in terms of technology or products backing them. Most altcoins use bitcoin's algorithm to develop their own blockchain network without having any particular solutions to solve gaps seen in the financial space.
Bitcoin is better because it solves and bridges gaps seen in the centralized financial systems.
