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?
