I believe this is your dream but that's fine. Dream can create hope and hope will make people try with their best skill to reach the target. Don't forget about stop loss because this is the limit you should not break. Market not same with mathematics but fundamental also take part, just try your strategy and good luck.
Apart from it being a dream, since no one can see the future anyway, there is still a good chance we get to see that become a reality based on certain development over time. I would not say $100k by 2020 cannot happen if we actually want to use the market movement so far to judge which one thing is over time I believe will keep increasing until we reach the level of mainstream level of adoption eventually.
Looking at the increase over the years, I would not doubt any possibility at the moment and for the fact that we will get to have another halving in 2020, we sure know what that has always caused in the market for the past ones.
