user4281: According to research by the University of Cambridge, the Bitcoin network currently consumes around 100 terawatt-hours of electricity annually, enough to run a country such as Sweden.
The second largest crypto-currency, Ethereum, suffers from similar energy problems.
Given Cardano's amazingly low energy consumption, coupled with the recent success of making the blockchain carbon neutral (see Cardano forest), would it be possible to move $BTC to the Cardano network and, if so, what would be the exact process?
Also, putting aside the interests of Bitcoin miners, what impacts would Bitcoin users experience and how could these be minimalised?
(I'm exploring these questions, and more, at https://twitter.com/cardanoclimate)

user2560: This is half joke, and I'm neither an expert in BTC neither in Cardano, but the minting of BTC could be controlled in cardano by a kind of virtual Proof of work, in which miners would register asics with serial numbers by means of authorized oracles. By assign a computing power for each asic model, the virtual PoW could set the minting rates of each miner according with the computing power that they have bought, without even running such computing power.

user4023: Potentially yes, but practically it doesn't make any sense.
This is a controversial question. Everyone has their own opinion on this matter.
Cardano has been using the Proof-of-Stake consensus mechanism starting from its birth. In PoS network validators use staking for earning money. PoS does not consume such a monstrous computational power required to mine blocks - which is why Bitcoin and Ethereum eat so much electricity. Miners perform calculations according to the Proof-of-Work (PoW) consensus mechanism. By the way, Ethereum developers are currently engaged in changing the network consensus to PoS – it'll take a lot of time.
I don't know if Bitcoin holders will be interested in the transition to PoS - I think not. Staking earnings (up to 5% per year) cannot be compared to mining earnings. After all, no one will deny that the price of Bitcoin is determined by the cost of ASIC mining equipment and the cost of consumed electricity.
