One million dollars may or may not happen. There are too many factors to consider, not the least is the number of viable alternatives. However, those who think it's a fantasy for btc to reach $10,000 are being unrealistic. We would only need a $100 Billion market cap to get close to that number. If history is any indication, btc could potentially achieve that in 5 years or less, depending (once again) on a multitude of factors. But it's very possible and one might even say quite probable. Btc went from a penny to $450+ in 6 years. That's an enormous increase
it went from $12 to $1244 in 11 months before
$10,000 could easily be reached early 2017.
$1,000,000 will obviously take a while longer, but we could see it as early as 2020.
The stable price before the big pump was around $120 in June or July. So that is about 10 times increase.
