Bitcoin’s 'Existential' challenge stems from its fundamental aim of financial freedom now clashing with increasing fragmentation. Originally a decentralized currency offering autonomy from traditional banking, Bitcoin now faces regulatory pressures and market volatility. These issues create divisions among users: some seek stricter regulation for stability, while others resist to preserve Bitcoin’s original ethos. This fragmentation threatens Bitcoin’s cohesive identity and long-term viability. The community must reconcile these differences to ensure Bitcoin’s survival and growth.
I am of the opinion that if there is too much clashing, nothing gets changed or upgraded, and bitcoin continues to function in its current form. It really doesn't need any upgrades. Sure, improvements to increase scaling sound great, but I'm always worried about the unintended consequences, so if no improvements come for a decade, its a sigh of relief in some ways.
As for miner centralization, yes, this can be a problem, but at the same time, if Bitcoin was dying, you would think miners would be leaving, and this could then decentralize it. I think the mining itself is decentralized, but the mining pools are where the centralization is. All of these miners can easily switch to a different mining pool in mere seconds. Its interesting to me that they don't, but I think if a real crisis ever came, the miners should be incentivized to switch.
As I have dug deeper into Bitcoin study though, I do have to wonder if there isn't a better way. Its good that so much compute is going to Bitcoin, because it prevents a big actor from that dreaded 51% attack. At the current hash rate, its impossible for anyone to acquire enough mining rigs or electricity, so that is good. But this also means that the biggest players get bigger and more powerful. Think of how many of us true bitcoiners would love to mine for the network, but it makes no practical sense. Don't get me wrong, I love the idea of PoW, but I also wonder if there isn't room to enhance this even further. Hear me out.
When it comes to voting, I have seen how everyone getting a vote sounds democratic, but is it really? US is bringing in illegal immigrants simply to be voters for the democrats. Voters will always go with the party who promises more free stuff. If you're not in the top 10% of income earners, you will likely want free stuff, because you think someone else is paying for it. I have also seen it suggested that the only people who should be allowed to vote are land owners because they have the most at stake. It makes sense because those people who don't have much will happily vote for new taxes on property. So when it comes to voting rights, we of course understand that a democratic process where everyone gets a vote makes sense, but some people are clearly too dumb to vote, and some people have more at stake, so their vote should almost count for more.
So I as a bitcoiner, who is holding bitcoin, would love to be able to decentralize mining and contribute to the hashrate, but I know that its not feasable given the current setup (and I would love to mine for Ocean). So I wonder if there isn't a better way. If I own 1 bitcoin, that is only 1/21M of the supply. But the biggest miners have a much smaller ratio of bitcoins to their hashrate. So wouldn't it be cool if there was some way to keep this proportion in sync? I think it introduces even more incentive to keep the network strong. No single actor could go after more hashrate if they didn't hold the bitcoin to in some way "prove" their allegiance to the network.
This way, the more that bitcoin is distributed around more holders, the higher chance there is that this distributes mining even more. With the current system, mining is only profitable for the biggest miners, and although we would like to think they are on the side of bitcoin, if they own very little, we have to question their motives, especially if they continue to point their hashrate to questionable mining pools. This is no different than people who vote for a president in a country in which they no longer live. Is it really fair to get a vote if you have not much of an allegiance to the country?
A 51% attack would never be possible because nobody will have 51% of the bitcoin, or at least of the bitcoin that you can point to as proof for adding so much hashrate. If you currently have 10 bitcoins lets say, and you lock up 8, this is only 8/21M, but when you think about who else is doing this, you might likely have 0.1% of the hashrate. (a small number, but not inconsequential) If you're currently a huge miner, and want to keep mining, you would have to buy more bitcoin to maintain your ratio, and this gives incentive to not do anything to the network to spoil it, like censoring transactions.
Its like like the way bitcoin is flowing into more and more hands, becoming more widely distributed, I would like to see mining distributed as well, but given the current incentives, its actually becoming somewhat centralized.
