It won't matter anymore when the next Bitcoin halving is here, that 6BTC per block will be reduced and a 110TH will have only 1% chance of solving a block compare to when it was 2%, the difficulty will rise more and the block will bring only 3BTC.
When the halving will happen only one thing is for sure, the reward will drop from 6.25 to 3.125.
Nobody knows what the difficulty will be and how it will react, but normally you would expect the difficulty to actually drop since there is less reward in mining, the revue drops also by half so some miners won't be that happy to mine anymore if instead of 10$ revenue with 6$ costs, you have 5$ revenue with $6 costs. It will depend a lot on what the prices are at that time and if even halving the profit margins would be enough to keep miners running.
But! for sure it won't mean the difficulty will double overnight!
As for the other free electricity issue, I knew I saw OP on another topic, so this is the "free" electricity some of you were curious about
@Charles-Tim 50% of my electricity fee per day is free because I have solar panels installed, mining from 9am to 6pm is 100 percent guaranteed, the rest will be on grid power.
I have good power bank too but with the power consumption of an s19 pro the bank up will only last me up to 4 hours.
