For more of the miners the only problem is high cost electricity so if you will have a cheap electricity or you will be able to manage for solar panel (free electricity) then yes it is worth and you will earn some good profit with mining. But stay away from cloud mining.
Indeed the fact is that the miners are paying a lot of money for the electricity and that is the problem of mining.
I think that mining is still worth it but I would not do it with the bitcoin anymore.
Mining is good and I think that its profitable and worth investing in it too but with the bitcoin its not worth it anymore indeed because of the fact that its not something that is easily done and due to the halving the gaining are not even profitable anymore..
