As a decentralized system by design, it can be difficult to see where the real power lies in Bitcoin. There are a number of different players in the ecosystem (e.g. miners, hodlers, exchanges, developers), but one entity has more power than the others in terms of what types of protocol improvements will be made.
the hodlers have the biggest impact on the bitcoin price due to the effect they have on the supply of available Bitcoin. Taking this point further, they also have the largest amount of power in terms of what types of improvements are made to the Bitcoin protocol because everyone in the system is incentivized to make the native tokens on the platform as valuable as possible.
There are many stakeholder like miners, hodlers, exchanges and developers are the one who have a big factors
affecting bitcoin prices, because hodlers can hold bitcoin that affects the circulation of bitcoin and i think exchanges is the biggest factors among the four reason stated above.
