I think its still worth to mine bitcoin since you can mine if you buy some cheap materials and also have a good apartment for space of your mining.
One ASIC miner isn't cheap lol and someone need to have many ASIC miners to mine Bitcoin for earn good amount of money. However he have a choice to mine a low cap coin, but of course the survivability and the price in the future is still a big question.
I would say mining Bitcoin isn't profitable anymore if you're a solo miner, only a big company are making money through Bitcoin mining.
Any asic has a daily profit, if the cost of electricity is adequate for mining. So why are you saying that a single miner does not make a profit? If you mine bitcoin in solo mode on one ASIC, then you will not earn, and if you are connected to the pool, then you will receive payments.
