I don't understand, the scam platforms indeed disrupted the good development of this market. That led more and more investors choose to buy coins not cloud mining even though the cloud mining is more stable.
Let's not talk about the scam platform but let us explore the halving, after the halving, the scenario will be quite different from the present situation, cloud mining will not be profitable as it is now, even if the cloud mining is legit it will have a hard time keeping up with the plan they first offered to their subscribers, there would be a lot of changes and on the plan.
After Halving Hashrate will drop. Difficulty will drop due to old miners are going away like S9s.
Cloud mining is very risky because there was so many cloud mining that has been collapsed before. Once you have physical hardware its different. You know that you own something. At least machine. Profitable or not you still own the asset. I would vote for holding physical machines in some professional facility or at home.
