Maybe I do not know for sure how bitcoin to be able to make me a millionaire because bitcoin prices continue to fluctuate. Perhaps to make me a millionaire in a year requires 100 bitcoin more. I hope the next 5 years the price of bitcoin is very good so that I could be a millionaire because if prices continue to rise bitcoin will be very easy to become a millionaire 
I hope so if the price will continue upward with this current trend than we have chance to become millionaire more early than this 5 years of period. Bitcoin is truly unpredictable in a year it gained more than 300X so maybe this could be possible to surpass $1000 in next 3 months.
