I have 0 posts! May I advice too???

Despite posts count those people are right. You will never see ROI neither with BFL nor Erupters. Better to speculate with BTC value.
In asic-gambling word it is crucial to have it on time. BFL prooved to not deliver on time (over a year delay lol)
And erupters are just overpriced.
Never said the advice new people were giving was bad. It is just funny seeing new forum members trying to help out their fellow bitcointalk friends!
