bitcoin start 2017 with 1,000$ and may end 2017 more than 10,000$ so if every year increase 1000% will reach 1M in less than 10 years .
it is dreams but bitcoin can do it.
If it increased 10 times each year, it would reach 1M much faster than in 10 years. In fact speed of increase loweres a little each year - you can see the figures on the graph, in the top line.
