Seeing that bitcoin has long been impossible to mine on a regular computer began to ponder the question of why the development team does not seek to switch to another algorithm to stop the mining of coins by large corporations and return to the canons that bequeathed Satoshi. It may be worth switching to the pos algorithm, you will not need to spend a huge amount of electricity and investors will be able to receive passive income for storing coins. There will also be no need to be afraid of the quantum computer. Interested in everyone's opinion.
