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.
And it is a need for them to push through and new mining machine in order to survive otherwise, they will lose the competition. It is to find that the more mining industry grows, the more they compete with each other and that who acquire the higher power machine will absolutely get the rewards. But unfortunately, they got the problem with their expense as it possibly will increase.
If this only the reason to put them on the work, those small scale miners will collapse.
