start pushing a campaign to engineer a rollback of the blockchain Vitalik style.
Vitalik hyped a centralized shitcoin that abandoned it's one USP ("code is law") the instant it was convenient for the rich creators. You can't compare that to Bitcoin.
If in the future ETF holders become the 99% and 1% are self-custodians, then it will be on their interest to push this agenda.
This will only be a concern if the ETF also owns 99% (or at least >51%) of the mining hardware. But, by the time they get into mining, they should also understand the importance of decentralization for trust in the Bitcoin network, and avoid this scenario from ever being possible.
What would happen? If in the future ETF holders become the 99% and 1% are self-custodians,
In a scenario where almost nobody owns bitcoin and things have gotten this centralized, we can say with confidence Bitcoin is already dead so who cares what happens!
Even if ETFs hold 99% of all Bitcoins in the future, I expect several competing ETFs to all have a fair share. Just like several mining pools have a large share of the market.
I expect we'll see another community split where new forked coin is created.
We'll get Bitcoin ETF (BTF), and normal real Bitcoin. One will be fully centralized and regulated, and one will be Bitcoin.
