i am having some opinions about if the bitcoin goes to the $750 at the beginning of December:
there are more companies using bitcoin related security services, and/or the termination of 500/1000 old Indian Rupee notes are not yet being eased.
guess what, don't be panic on buying excessive bitcoins right now, don't be a greedy. if you bought bitcoins, better go long.
I think it already proven in that date, the price just reach $750 and keep rising until now even there is decreases too, but at least the price looks good for now. We might see in this month bitcoin price hit $800, as people want to buy more bitcoin due to Christmas and new year gifts.
