The first mover benefit is probably the biggest issue I see with Bitcoin. When I think of advances in technology and services I don't feel the first adopters get a locked in advantage that other people can't match or surpass.

There can be some benefits to being early such not needing to fight for attention as hard on a new social platform. But plenty of people put in work and grew things like YouTube channels bigger than many old first adopters. But other services and tools just wait to be used and generally provide their value immediately once adopted

Bitcoin just doesn't feel that way. The value proposition here is... value itself. There just aren't many options to leverage this technology other than being early and waiting. You can only make up for lost time by dumping an equivalent amount of money into it now to make up for lost time.
