1) would you mine
2) if so, mine with what? (considering vendors ASIC queues), difficulty, etc from a budget of few hundreds.
3) if all the above is positive, it it important to invest more to get better return?
1) I would have mined a bit but just to get startup capital to do more bussinesses.
2) GPUs until that died
3) no it is better do small investments and then when the returns are good make them bigger. Has yet to fail me.
