It is really possible, we are here in this crypto world to earn money so we are looking for the bitcoin to go up so we can earn more, but it all depends on the thinking of person if he wants to earn money while the value of the bitcoin is high or he wants to earn money every time without thinking whether the price of bitcoin is down, it is a matter of thinking of different people in this crypto world.
Professional miners regularly pay high amount of electricity bills t o keep their mining rig live and i don't think all of them will follow the way of "Mining for nothing". They have their initial and regular maintenance costs where due to halving they are not getting enough funds to backup all. So its simple that a big number of miners will shut down their rigs due to insufficient mining rewards and that will remain same until bitcoin's price show enough uptrend move.
As a crypto user or trader you can stay sticky with bitcoin with the idea of supporting bitcoin but its kinda different for miners. Honestly it was expected that miner will leave the field for sometime but matter of concern is the number of miners.
