Their is no leadership of bitcoin, meaning no one to coordinate a conversion to PoS.
You also have the PoW cult members that cry when anyone mentions Proof of waste is about to be banned.
You are wrong, it is not the lack of a leader that stops BTC conversion to the POS, even if Satoshi was here he surely would not act like Vitalik

. Proof of stake is just another centralized algorithm that will make BTC one of the many centralized shitcoins in the market, and neither the devs, miners, nodes or BTC users want that.
Look to a PoS coin , if interest is what you are looking for,
You mean a centralized, censoring shitcoins?
the bitcoin community is unable and unwilling to fix their coin problems.
If decentralization is the "coin problem" you mean, then we don't want it fixed!
