I see a bright future for bitcoin. It definitely hasn't quite reached its full potential yet, although I think $250,000 by 2020 is a little bit optimistic. With the possible UASF changes being implemented on August 1st and now Bitmains UAHF, things could get quite interesting in a short space of time. I think around that time might present some good opportunities to buy low as uncertainty rises.
To people thinking it's too late to get in on bitcoin, just invest a little, you never know. That $100 you invest may grow into a considerable amount over a period of years.
