It's code that functions by taking in revenue and paying out in a trustless way.  That's a business without a manager.

Bitcoin "Core" had a core team of devs too, (who did nothing but purposefully wreck it) so just having devs doesn't make it centralized unless you're saying Bitcoin is/was centralized as well.

Further, Bitcoin is free floating also, as are all assets including the US dollar.  Value is subjective and exists in the mind of consumer.  This can not be fixed in time.
