Hello guys.Soon im starting with mining and i want to know something.First can i mine solo because i have just one rx580 8gb.Do i need to mine on pool or not?Here on mining calculator it says that with 30mhs 140w from wall and cost of electricity 0.03 i can earn about 80$ on ethereum(price of eth is about700),is that true?If some1 know please tell me,and how do blocks affect solo mining(will i learn much less than mining on pool,and what about tax?).Sry for my english.
