I agree, especially with crypto. Extra time to research can save a person for getting into a bad investment. Mining hardware can do you right or completely waste your time and money due to the rate of progress in the technology. USB miners are good for little side learning, maybe add a few small hasshes to your mix but trying to mine on them solo is just a huge waste of time at this stage sadly. I just wish they would stop trying to pawn off dated miners on users out there
