Mining might not be so profitable for some miners now after halving so it's likely to happen.
Perhaps, if they are still getting profits, they will still continue mining, but I am pretty sure that hardware impacts their decisions as well, according to this
article: Mining rigs that are old enough, isn't as effective as those that are new, built more efficiently. This means that these mining rigs aren't gaining profit because of the huge consumption of electricity, unless, if there is free electricity. In addition, bitcoin rewards decreases significantly, pushing the miners away and it is really happening.
Mining with a less block than usual is going to rip off the small miners, they cannot run simultaneously with the bigger ones that has a latest devices for mining. What the new hardware for mining has an added energy consuming efficiency which is needed right now because of a high electricity rates that we have. I don't think from now on, there are still small miners that is mining bitcoin or they are still trying and testing so they can calculate the expenses and generated income.
