What is funny ,
is you still don't understand it.
Imagine who will do everything when you will move from POW to POS? Is there a team? It's not like a hard fork that anyone can do it. Will the community accept this migration? Can you shut down old chain miners who don't want to stop themselves? How will you control them? If miners continue mining then the old chain still will be live. Due to true decentralization, anyone can't move Bitcoin from POW to PoS? There will be many more questions definitely during the move. So it's quite impossible.
Exactly,
It is impossible for BTC to convert to PoS, because their is literally no one in charge to coordinate the change.
Which means when the US & Europe ban Proof of Waste, the only options are utter destruction of btc or becoming a token on a PoS network before the crash.
However, 4 mining pool operator control over 51% hashrate, 4 people colluding is centralized.
But the pool operators only centralize the transactions control, the code development is still rudderless.
One has to wonder ,
If Proof of Waste is not a doomed tech.
Why does none of the new coins use Proof of Waste.
Mining is a commitment, because you often have to buy specialised hardware.
Good coins are more than the sum of their mechanisms.
As for Ethereum
You kind of just rambled.
So if a dummy buy an asic, he can mine BTC & Bitcoin Cash until the PoW bans take place.
But if an Investor buy a PoS coin, it can literally only stake that single coin.
Hate to break it to you the staking coin is more specialized than the mining asic.
PoS coins don't waste energy, PoW coins do waste insane amounts of energy.
Energy that people could be using to heat/cool their homes, or use for cooking or refrigeration.
Energy that people need to survive and have a decent life.
As for Ethereum, by converting to PoS,
it is more secure, less energy-intensive, and better for implementing new scaling solutions compared to the previous proof-of-work architecture.
And here is a biggie for you,
Ethereum PoS is totally immune to the coming Proof of Waste Bans.
You know why all of these topics about converting BTC to PoS keep popping up.
The BTC masses are not as stupid as the BTC cult nutjobs,
a few of them are starting to realize , hey what happens to my btc once the US and Europe ban PoW mining.
(They can see it coming.)Some think, a quick conversion to PoS ,
and that can't happen due to the lack of leadership in btc development.
So thinking PoS is going to save BTC network is not going to happen.
Once the PoW Bans are enacted, there won't be 2 years to start the conversion, figure out what PoS code is required,
what change to make or not make to the reward system, whether or not to become deflationary by burning transaction fees.
The BTC community is literally incapable of a successful conversion.
So that only leaves wrapped tokens, which is already being used,
https://wbtc.network/Wrapped Bitcoin delivers the power of Bitcoin
with the flexibility of an ERC20 token
Wrapped Bitcoin (WBTC) is the first ERC20 token backed 1:1 with Bitcoin.
Completely transparent. 100% verifiable. Community led.
https://www.tronweekly.com/cardano-wrapped-bitcoin-boost-adoption/The only other option will be to just let btc death spiral.
