I should have said miners and developers. Of course you need the hashrate too, but that can be bought. If ETF-BTC can promise higher valuations, miners may follow, since they are economic actors that seek profit. If the majority of economic activity is happening on ETF-BTC, they may get more from the fees in there. As far as developers, we have developers fucking with our money in the form of Ordinals already. They could also buy people like Elon Musk type PR to pump their hardfork. They could also buy lobbysts to pass laws that outlaw non ETF-BTC for enabling money laundering or whatever. Im sure that's their long term goal with all of this actually. Does anyone seriously think they have approved ETF's if they don't think they can use it to control BTC? Their motto has been "We'll tame Bitcoin" for years now. This is all part of the plan. The question is, if community of actual BTC holders will fall for it. At the end of the day, in any hardfork both sides get shares of each token, so we'll see who dumps on who.
