I think the maximum possible bitcoin price is around 5000-10000. But it's not guaranteed we reach it.
This is hard to say. From what I know, if bitcoin circulation equaled the dollar it would be worth 98,000. This is highly unlikely but if you factor in other currencies and realize this is world currency the numbers can get rather high. I would be surprised through if we cross 10,000 in the next year. Maybe 2-5 years. Just my guess.
Anyone have the calculations for astronomical numbers people throw around on here. Such as the unbelievable claim of bitcoins potential of being worth 1,000,000.
