Really depends on the location where you are mining in terms of energy costs. In China and Island the conditions are good and the energy is cheap, so there it should still be profitable. In other countries like Germany, where the energy costs per kWh are quite high, mining (at least bitocin mining) is not profitable anymore.

I remember when China is the biggest miner of bitcoin but now they banned the cryptocurrencies there because they cannot control it because of the decentralization but if we will back to the question, it is worth it only for the people who can wait for at least 1-2 years before thinking about their ROI because it is not that fast profiting investment.
