if quantum computing cracked encryption, everything secured on the internet would be in trouble, not just btc
every 4 years there is a halving event where the btc reward is cut in half. Eventually all btc will be mined and the only role of miners will be to process transactions and they get to keep the fees. that will be the incentive
i agree, Ethereum might be the better approach.
i'm not too concerned about the electricity usage in the long term. for btc it will be less and less profitable for miners to operate consuming large amounts of energy. as the price plateaus and mining rewards decrease, energy consumption should also plateau. that is if energy price stays the same and doesn't become cheaper.
