My understanding of bitcoin is that the miners are the ones keeping bitcoin decentralized. What happens when only the richest of people can afford mining?

  • Your question caused the authors of this paper to conclude that "the bitcoin 4-year reward halving system [is] very disturbing."

  • I have the same concern and for me it shows how undefined the space is, which is good I guess. If the community is dynamic and progressive then who knows. It's in the people's hands apparently? Confused actually.

This is a valid concern and I think nobody can give you a clear answer here. We'll just have to wait how it evolves and how people react; it is an unclear future.

There are some ideas about changing the proof-of-work algorithm to make mining pools not that profitable, but the effects of such implementations could be various.

I highly recommend this article from Vitalik Buterin, where he walks through the history of Bitcoin mining, explains problems and solutions encountered in the past and describes the situation today. He also dares to predict the future development and provides some ideas to keep the mining decentralized.

It seems there's still a long path in the future of Bitcoin development.
