Well they say Bitcoin and crypto is the future. My biggest fear is a new innovation will come out that bypass all hindrances to financial transparency and decentralization. We dont know yet what is there to come so if ever theres a new tech that introduced that surpasses the ability of bitcoin and other and lead to migration to this new one which I believe not present yet (Hope not yet).
I don’t see this as a problem or thing to be scared of, I think the major reason why bitcoin was invented was to make way for financial freedom, transparency and decentralization and that doesn’t mean it will be in any competition with any currency so just in case we got to a position where a better technology comes which betters this use case then it wouldn’t be a problem rather we will embrace it too and use each for it’s cause because as far as I know, no matter the outcome bitcoin will still have its value and use case.
Yes Bitcoin protocol remains decentralized but there are points that could be centralized like
Mining centralization
Node centralization
Not to mention Layer 2 centralization is possible.
Yes the Protocol is still centralized but something's related to it are centralized.
The protocol will remain decentralized because the centralization of the miners or such cannot rewrite the script on it. I get that bitcoin mining is a bit more centralized this days to some big mining pools but as long as there is other mining pools no matter how small too the censorship can be curtail and aside censorship of transactions I don’t have any much fear with others. Node cannot be centralized because we all are node runners and most of us cannot be centralized which is also major reason why decentralization of the network will still go on for as long as I can remember. The only scare is that mining centralization and even that I don’t foresee in a short period of time maybe until after mining ends and it is not long too profitable for even smaller pools to run again
