1. How much money do you have currently, to buy mining hardware? 2. How much value (in crypto, of some kind) you expect to have? Answer those questions will give you the way: A. Doing hobby mining with some general mining software / hardward (your GPU, CPU, well) B. Doing heavy mining with a mining rig (GPUs), farm of it C. Doing super heavy mining with a farm of ASIC Of course each way only fit certain, with BTC, for example, without ASIC now, it's just the waste of money (bill for energy and burning out of GPUs)
