In summary, mining uses a lot of electricity, places a downward pressure on the Ethereum price from miners selling, and inflates the outstanding number of Ethereum. With the Merge, all Ethereum transactions will switch over from being added by miners to being added by the Beacon Chain. Some even believe that Ethereum will become deflationary after the Merge, meaning that outstanding Ethereum will slowly decrease in the absence of miner rewards since Ethereum transaction fees are burned.
