I don't have much knowledge about mining but I heard that mining cast high quality and very expensive electricity, and most of miner got lost their money because of lack of knowledge and wrong planing.
could anyone here tell me is ethereum mining really worth?
Minning ETH is only worth if you have free electricity or very cheap electricity. In my country, electricity is so expensive that i cant even think of even a New Alt coin mining whose difficulty is very low.
I would suggest safe way to grow bitcoins is trading Bitcoins with Altcoins and vice versa.
Better to stay at bitcoin because i heard that ethereum will be down soon. its better to stay away and clarified if ethereum will dump again because we experience of bad thing about that before..
