I wouldn't say that it is possible to get a millionaire in 2 months, but if you have a basic understanding of day trading and can make 5% a day... u reach the goal i guess in 2 years. But u have to be patient, that's the biggest problem of all bitcoin traders.
Not all have that high level of patience to wait for 1 year to earn 1 btc as everyone here wants to make quick money and that's what everyone dreams off but everyone forgets the reality that its not easy to get rich overnight and you need to have patience to achieve your goal.
Being rich overnight is impossible. During the early days most of the people have such a thinking and the same got changed much. Now people know that it's not that simple to buy and just become rich. As every form of investment, surely patience is must to get the best outcome through bitcoin. If one or two bitcoin is the focus then large volume of bitcoin needs to be there for all sorts of trading.
