In one year the price rose with 800% {that is a BIG achievement} Let's say this will happen for the next 3 years until 2020.... then we will have a
price of $72 000 for 2018 and $576 000 for year 2019 and finally $4 608 000 for year 2020. This is not achievable at all at the current growth
rate. So $500 000 per bitcoin sounds impossible, but it is not too far fetched.
{hope my math is correct}
